Grades K-2 or Adult Naive Learner

NGSS Connections for Teachers
Concept Boundaries for Scientists

Have you noticed that everything alive needs water? Your pets, trees, and your family, too. So why do you think that is? It’s true that our bodies and other living things are made from all sorts of different things but water makes up a lot of it. Also, when you look at a globe of Earth, there really is a lot of water! Scientists have found that all living things need water. So, if we would like to try to find living things from some other planet, then maybe we should look for places that also have water.

Disciplinary Core Ideas

LS1.C: Organization for Matter and Energy Flow in Organisms: All animals need food in order to live and grow. They obtain their food from plants or from other animals. Plants need water and light to live and grow. (K-LS1-1)

ESS3.A: Natural Resources: Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do. (K-ESS3-1)

LS2.A: Interdependent Relationships in Ecosystems: Plants depend on water and light to grow. (2-LS2-1)

ESS2.B: Plate Tectonics and Large-Scale System Interactions: Maps show where things are located. One can map the shapes and kinds of land and water in any area. (2-ESS2-2)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form. (2-ESS2-3)

Crosscutting Concepts

Patterns: Patterns in the natural world can be observed. (2-ESS2-2),(2-ESS2-3)

Big Ideas: Water is critical for life. Living things are made up of water. When looking for life beyond Earth, places that have water are of great interest.

Boundaries: Students in this grade band describe patterns of what plants and animals (including humans) need to survive. Examples of patterns could include that animals need to take in food but plants do not; the different kinds of food needed by different types of animals; the requirement of plants to have light; and that all living things need water. (K-LS1-1)

K-8 Water in the Biosphere. In this one-hour lesson, students make their own qualitative observations outdoors. Then they examine the life they saw and how water in the biosphere is part of the greater water cycle on Earth. This lesson can stand alone or be a part of a larger unit which includes the water cycle, Earth’s water and interacting spheres. NASA . https://pmm.nasa.gov/education/lesson-plans/water-biosphere

K-8 The Water Cycle. In this one-hour lesson, students participate in a web quest to learn about the water cycle, and then build a mini-model of the water cycle to observe how water moves through Earth’s four systems. This lesson can stand alone or be a part of a larger unit which includes the water in the biosphere, Earth’s water, and interacting spheres.

Grades 3-5 or Adult Emerging Learner

All living things on Earth need water. Everything from people, plants, animals, and even mushrooms and things too small to see need water to survive. Even things like cacti in a desert need some water to live. Water seems to be very important for life. Have you ever looked at a globe – there is a lot of water! Since all living things that we know of need water and many of us want to know if there could be other living things out there beyond Earth, then one thing we can do is investigate places with water beyond Earth. Mars had rivers and lakes of water a long time ago and there could still be some water deep underground there today. Also, there are some moons around other planets that have lots of water. We need to continue to investigate these places and more because if there is water, then there might be life, too.

ESS2.A: Earth Materials and Systems: Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity break rocks, soils, and sediments into smaller particles and move them around. (4-ESS2-1) *Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather. (5-ESS2-1)

ESS2.B: Plate Tectonics and Large-Scale System Interactions: The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near their edges. Maps can help locate the different land and water features areas of Earth. (4-ESS2-2)

PS3.D: Energy in Chemical Processes and Everyday Life: The energy released [from] food was once energy from the Sun that was captured by plants in the chemical process that forms plant matter (from air and water). (5-PS3-1)

LS1.C: Organization for Matter and Energy Flow in Organisms: Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion. (5-PS3-1) *Plants acquire their material for growth chiefly from air and water. (5-LS1-1)

LS2.A: Interdependent Relationships in Ecosystems: The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants.

LS2.B: Cycles of Matter and Energy Transfer in Ecosystems: Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. (5-LS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Nearly all of Earth’s available water is in the ocean. Most freshwater is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere. (5-ESS2-2)

Systems and System Models: A system can be described in terms of its components and their interactions. (5-ESS2-1, 5-ESS3-1)

Big Ideas: All living things on Earth need water. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. In the past, Mars had an abundance of water and it still has water today as do some of the moons around other planets in our solar system. These may be the best places to find life outside of Earth.

Boundaries: Students in this grade band are learning to graphically represent the distribution of water on Earth, including its oceans, lakes, glaciers, ground water, and polar ice caps. (5-ESS2-2)

Grades 6-8 or Adult Building Learner

One attribute that is common to all living things that we know of is the need for water to survive. Even organisms that live in very dry places need water to live. Why? Why is water so important to living things? One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get energy in and to move waste out.

Water is made up of two atoms of hydrogen and one atom of oxygen that make a molecule. But water is a certain type of molecule called a “polar molecule”. Polar molecules have one side of the molecule that’s a bit more positively charged and the other side a little more negatively charged. This allows water to more easily break apart or dissolve other molecules. That’s why you can dissolve salt in water! There are actually a lot of other liquids that can do this but water has other advantages as well. Water is very plentiful. About 70% of the surface of Earth is covered by water, from our oceans and our lakes to our rivers and streams. It turns out that water is also plentiful in the solar system. Comets have a lot of water within them, there is ample evidence that liquid water existed on ancient Mars in great quantities, and many moons have water under their surfaces.

Water is super important for life as we know it! There might be other forms of life out there that don’t rely on water the way we do, but looking for alien life in places with lots of water is one good way to start searching for possible extraterrestrial life.

LS1.C: Organization for Matter and Energy Flow in Organisms: Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (MS-LS1-6)

PS3.A: Definitions of Energy: The term “heat” as used in everyday language refers both to thermal energy (the motion of atoms or molecules within a substance) and the transfer of that thermal energy from one object to another. In science, heat is used only for this second meaning; it refers to the energy transferred due to the temperature difference between two objects. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

PS3.D: Energy in Chemical Processes and Everyday Life: The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen.

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water’s movements — both on the land and underground — cause weathering and erosion, which change the land’s surface features and create underground formations. (MS-ESS2-2)

ESS3.A: Natural Resources: Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. (MS-ESS3-1)

Structure and Function: Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function. (MS-LS1-2)

Big Ideas: All living things on Earth need water. It is critical to cellular function. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. As a polar molecule, it has specific chemical properties, like the ability to dissolve other molecules. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, astrobiologists look for water on other worlds as an indicator of possible life.

Boundaries: Students in this grade band construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes. Emphasis is on how these resources are limited and typically non-renewable. (MS-ESS3-1)

8-10 SpaceMath Problem 121: Ice on Mercury? Since the 1990’s, radio astronomers have mapped Mercury. An outstanding curiosity is that in the polar regions, some craters appear to have ‘anomalous reflectivity’ in the shadowed areas of these craters. One interpretation is that this is caused by subsurface ice. The MESSENGER spacecraft hopes to explore this issue in the next few years. In this activity, students measure the surface areas of these potential ice deposits and calculate the volume of water that they imply. [Topics: area of a circle; volume, density, unit conversion] https://spacemath.gsfc.nasa.gov/planets/4Page23.pdf

Grades 9-12 or Adult Sophisticated Learner

All life on this planet needs water to survive. Some life can live with very little water in extremely dry places but they still need water. As we strive to find life beyond Earth, it is important to consider what life on Earth tells us about where to look. Why is water so important for life? Water supports cell functions. All organisms are made of cells, from microbes to the largest animals. All of life’s functions are completed within cells. Life needs chemical reactions to take place in order to gain energy, grow, and get rid of waste. Water is a liquid which allows the chemistry of life to take place. It is also a polar molecule which allows most other molecules to be dissolved. Because of this, we call water a “solvent”. Having such a good solvent as water is critical for the functions of life. But there are also some other reasons why water is so important:

Water is plentiful! Hydrogen is the most plentiful element in the universe and oxygen the most plentiful in Earth’s crust. On Earth, about 70% of the surface is covered by water. But there’s also lots of water in other places in our solar system. For instance, we’ve found many lines of evidence that lots of water existed on the surface of Mars during its early times, and Mars currently has a lot of frozen water under its surface. Comets contain mostly water ice. There are lots of moons in our solar system that are made of a lot of water ice, and there are even some moons with liquid water oceans under their icy crusts (like Europa and Enceladus).

Water still has other advantages as a solvent for life. For instance, water stays in the liquid phase over a large range of temperatures compared to some other solvents. That allows more places to have the potential for liquid water. It also has a high heat capacity. This means that water offers some protection to organisms from quick or drastic temperature changes.

Water also has an interesting property with regard to the density of ice. For many molecules, the solid has a higher density than the liquid. So, for most molecules, the solid would sink in the liquid. But this isn’t the case with water. For water, ice is actually less dense than liquid water. This is why ice floats! If this didn’t happen, then all of the organisms that live in the bottoms of lakes in the winter time would be completely frozen. But, even worse, during times in our planet’s history when the world has become very cold (causing what we call Snowball Earth), if frozen water sank, then all of Earth’s ocean life would have become frozen and maybe died!

If we want to understand how life works, then it’s really important to understand the chemistry of water. And astrobiologists who are wondering if we’re alone in the universe need to be aware of the potential for water to be important for other kinds of life as well. Right now, we’re investigating worlds like Enceladus and Europa, Mars, and other solar system bodies that show signs of water. Also, beyond our solar system, we’re looking for exoplanets that have the potential for liquid water at their surfaces, since they might be important places for us to look for possible extraterrestrial life.

PS3.A: Definitions of Energy: Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. (MS-PS3-1) ▪A system of objects may also contain stored (potential) energy, depending on their relative positions. (MS-PS3-2) Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

LS2.C: Ecosystem Dynamics, Functioning, and Resilience: Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health. (MS-LS2-5)

ESS2.A: Earth’s Materials and Systems: All Earth processes are the result of energy flowing and matter cycling within and among the planet’s systems. This energy is derived from the Sun and Earth’s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth’s materials and living organisms. (MS-ESS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land. (MS-ESS2-4) ▪ Global movements of water and its changes in form are propelled by sunlight and gravity. (MS-ESS2-4)

ESS2.D: Weather and Climate: Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns. (MS-ESS2-6) The ocean exerts a major influence on weather and climate by absorbing energy from the Sun, releasing it over time, and globally redistributing it through ocean currents. (MS-ESS2-6)

Stability and Change: Much of science deals with constructing explanations of how things change and how they remain stable. (HS-ESS2-7)

Big Ideas: All living things need water. Water is critical to cellular function, chemical reactions, and thermal regulation. Water is less dense when a solid and stays in the same state over a wide temperature range. It is abundant on Earth and a common thread between all living things. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, Astrobiologist look for water on the surface and atmosphere of exoplanets as an indicator that the planet could support life. Understanding the chemistry of water is important to understanding how life works.

Boundaries: In this grade band, students investigate the properties of water and its effects on Earth materials and surface processes including chemical investigations like chemical weathering and recrystallization. (HS-ESS2-5)

Storyline Extensions

Water is so cool.

The range of temperatures at which water stays liquid is rather large compared to most other common solvents. For instance, at sea level methane freezes at -182 Celsius © and boils at -162 C (a range of 21 C) and ammonia freezes at -78 C and boils at -34 C (a range of 44 C), meanwhile water freezes at 0 C and boils at 100 C (a range of 100 C). This means that the range of temperatures where water is liquid is more than twice that of ammonia and almost five times more than that of methane.

Water has a high surface tension. This means that that the molecules at the surface of a body of water are attracted to each other and hold each other together. You can see this yourself by filling a glass with water to the very tippy top and then seeing how many more drops of water you can get into it. You’ll be surprised to find that you can actually get a good bit more water into the glass! The high surface tension of water is also why some insects, like water striders, are able to move around on top of water without sinking into it. It also is related to something called “capillary action”, which is used by many plants to draw water up from the ground against gravity.

It’s actually really rare for a solvent to be more dense as a liquid than as a solid. We know of other elements and molecules that are more dense as liquids, but it’s far more common for the solid form of a substance to be more dense.

[note: this is fairly advanced] Oxygen is a member of the group of elements known as the “oxygen family” (also sometimes called the chalcogens). These are the elements in the periodic table that are in group 16 (the vertical column starting with oxygen and going down). They include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). All of these elements can form bonds with two hydrogen atoms. However, none of the other chalcogens come close to oxygen in its large range of temperatures where it is a liquid. This is because oxygen is much more electronegative (much greedier for electrons) and makes a far more polar molecule than the others. This greater polarity leads to stronger hydrogen bonding and the greater range of temperatures for liquid water.

45+ ways to conserve water in the home and yard.

How to save time and energy around your home while spending less on your water bill.

Water conservation has become essential in all regions, even where water seems abundant. That’s because our water resources are finite, and they are getting smaller every year. Use our guide to save more water, both indoors and in your garden and yard.

Why Conserve Water? Water Conservation in the Home … Water Conservation in the Yard & Garden Water Conservation Summary

Why Conserve Water?

In addition to saving money on your utility bill, water conservation helps prevent water pollution in nearby lakes, rivers, and local watersheds. Conserving water also prevents greenhouse gas emissions associated with treating and distributing water.

Water Conservation in the Home ...

The most effective way to save water is to upgrade to efficient fixtures. But there are other ways to help reduce the amount of water you use at home.

Don’t Use the Toilet as an Ashtray or Wastebasket Every time you flush a cigarette butt, facial tissue, or other small bit of trash, you’re wasting gallons of water. Put them in the garbage, or better yet, recycle.

Put Plastic Bottles or a Float Booster in Your Toilet Tank To cut down on water waste, put an inch or two of sand or pebbles inside each of two plastic bottles. Fill the bottles with water, screw the lids on, and put them in your toilet tank, safely away from the operating mechanisms. Or, buy an inexpensive tank bank or float booster. This may save ten or more gallons of water per day. Be sure at least three gallons of water remain in the tank so it will flush properly. If there is not enough water to get a proper flush, users will hold the lever down too long or do multiple flushes to get rid of waste. Two flushes at 1.4 gallons are worse than a single 2 gallon flush.

Buy an Adjustable Toilet Flapper Installing an adjustable toilet flapper will allow for adjustment of each per flush use; the user can adjust the flush rate to the minimum per flush setting that achieves a single good flush each time.

Install Low or Dual Flush Models Federal regulations state that new toilets must use no more than 1.6 gallons per flush. Replacing an old toilet with an ultra-low volume (ULV) 1.6 gallon flush model represents a 70% savings in water and will cut indoor water use by about 30%. Alternatively, consider purchasing a dual flush toilet or installing dual flush converter that turns a standard toilet into a dual flush toilet, saving an average family 15,000 gallons of water each year. More water can be used when it’s needed, but for most flushes you’ll be using 70% less, adding up to some significant water savings.

Install Composting Toilets Composting toilets are the most effective way to cut water waste from your bathroom since they require no water at all! Better still, they keep all the nutrients and pollutants out of waterways and make them available for use in non-food landscapes. Check codes in your area to be sure they’re legal before installing one. Read our article about composting toilets to find out if they’re right for you.

Use Clothes Washer for Only Full Loads With clothes washers, avoid the permanent press cycle, which uses an added 5 gallons (20 liters) for the extra rinse. For partial loads, adjust water levels to match the size of the load.

Consider a High Efficiency Washing Machine The most efficient washing machines use as little as seven gallons per load, compared to a whopping 54 for a traditional washer. A high efficiency (HE) washer should easily pay for itself over its lifetime in water and energy savings. New Energy Star rated washers use 35 – 50% less water and 50% less energy per load. If you’re in the market for a new clothes washer, read our article about water-saving frontload washers .

Install Water-Saving Showerheads, Shower Timers, and Low-Flow Faucet Aerators Inexpensive water-saving low-flow showerheads or restrictors are easy for the homeowner to install. Long showers can use five to ten gallons every unneeded minute. “Low-flow” means it uses less than 2.5 gallons per minute. You can easily install a ShowerStart , which automatically pauses a running shower once it gets warm.

Take Shorter Showers One way to cut down on water use is to turn off the shower after soaping up, then turn it back on to rinse. A four-minute shower uses approximately 20 to 40 gallons of water. You can also install a simple shower timer, available from your local water utility or hardware store.

Faucets and Sinks

Fit Household Faucets with Aerators This easy and effective home water conservation method is also the cheapest! A simple low-flow aerator saves water in the bathroom.

Turn Off the Water After You Wet Your Toothbrush There is no need to keep the water running while brushing your teeth. Just wet your brush and fill a glass for mouth rinsing.

Rinse Your Razor in the Sink Fill the sink with a few inches of warm water. This will rinse your razor just as well as running water, with far less waste of water.

Minimize Use of Kitchen Sink Garbage Disposal Units In-sink ‘garburators’ require lots of water to operate properly, and also add considerably to the volume of solids in a septic tank, which can lead to maintenance problems. Start a compost pile as an alternate method of disposing food waste.

Opt for the Dishwasher Over Hand Washing It may seem counterintuitive, but it turns out washing dishes by hand uses a lot more water than running the dishwasher, even more so if you have a water-conserving model. The EPA estimates an efficient dishwasher uses half as much water, saving close to 5,000 gallons each year.

When Washing Dishes by Hand, Don’t Leave the Water Running for Rinsing If your have a double-basin, fill one with soapy water and one with rinse water. If you have a single-basin sink, gather washed dishes in a dish rack and rinse them with a spray device or a pan full of hot water. Dual-swivel aerators are available to make this easier. If using a dishwasher, there is usually no need to pre-rinse the dishes.

Don’t Let the Faucet Run While You Clean Vegetables Just rinse them in a stoppered sink or a pan of clean water.

Keep a Bottle of Drinking Water in the Fridge Running tap water to cool it off for drinking water is wasteful. Store drinking water in the fridge in a safe drinking bottle . If you are filling water bottles to bring along on outdoor hikes, consider buying a personal water filter, which enables users to drink water safely from rivers or lakes or any available body of water.

Check Faucets and Pipes for Leaks A small drip from a worn faucet washer can waste 20 gallons of water per day. Larger leaks can waste hundreds of gallons. Some faucet leaks are easily spotted, but others take a little more effort to locate. Dry sinks and tubs thoroughly and allow to sit for an hour. If you notice wetness, you’ve found a leak. To find leaks from faucet handles, dry the area around them before running water. You’ll see water collecting next to them if there’s a leak.

Check Your Toilets for Leaks Put a little food coloring in your toilet tank. If, without flushing, the color begins to appear in the bowl within 30 minutes, you have a leak that should be repaired immediately. Most replacement parts are inexpensive and easy to install.

Use Your Water Meter to Check for Hidden Water Leaks Read the house water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.

Extending Your Conservation Measures

Insulate Your Water Pipes It’s easy and inexpensive to insulate your water pipes with pre-slit foam pipe insulation. You’ll get hot water faster plus avoid wasting water while it heats up.

Recycle Your Water Where You Can Collect the cold water you run before it’s hot enough to shower and use it to water plants or flush the toilet (known as a bucket flush). Rinse water from dishes and food preparation can be collected and used to soak other dishes.

Eat Less Water-Intensive Foods Our diets account for roughly half of all the water we use. All food has a water footprint, but some are much larger than others. Eating less beef, one of the most water-intensive foods, is a smart place to start. Shifting away from animal products to a plant-based diet can shrink your water footprint significantly.

Buy Less Consumer products are an often-overlooked source of water use, accounting for up to a third of most people’s water footprint. Buying less of everything—from clothing to electronics to household goods—can dramatically decrease your water footprint.

Water Conservation in the Yard and Garden ... Outside Your Home

Don’t run the hose while washing your car.

Clean the car using a pail of soapy water. Use the hose only for rinsing; this simple practice can save as much as 100 gallons when washing a car. Use a spray nozzle when rinsing for more efficient use of water. Better yet, use a waterless car washing system; there are several brands, such as Eco Touch, which are now on the market.

Use a Broom, Not a Hose, to Clean Driveways and Sidewalks

Blasting leaves or stains off your walkways with water is one way to remove them, but brushing with a broom to first loosen the dirt and grime will decrease your water use and save you time in the long run.

Cover Swimming Pools to Reduce Evaporation

Swimming pools can lose an inch or more of water each week to evaporation. Temperature, humidity, wind, and the way the pool is situated can all affect how quickly water evaporates. To save thousands of gallons of pool water each season, get a cover for your pool.

Check for Leaks in Pipes, Hoses, Faucets and Couplings

Leaks outside the house may not seem as bad since they’re not as visible. But they can be just as wasteful as leaks indoors. Check frequently to keep them drip-free. Use hose washers at spigots and hose connections to eliminate leaks.

Reuse Wastewater Where Possible

“Grey water” is the water draining from your house’s sinks, bathtubs, and laundry machine, which can be used to water plants (as opposed to “black water” from toilets, which needs to be treated).

You can harvest grey water in a small way with a bucket in your kitchen or shower, or install a grey water system, which reroutes water from your drains to your landscape. Though not yet legal everywhere, codes are changing to allow more people to take advantage of this source of otherwise wasted water. The simplest systems harvest only water from the washing machine , which can add up to thousands of gallons per year. If you use grey water in your landscape, be sure to use only eco-friendly and plant-based soaps and cleaners in your home so you’re not dousing your plants with industrial chemicals.

Vegetable Garden

Maintain Your Irrigation System If you use an irrigation system, check that it’s operating correctly toward the beginning and end of each season. Clear any visible clogs, and adjust the settings according to the needs of your plants and the time of year. Plants will need less water in cooler weather and more in hotter weather, and correct settings will not only save water but ensure that plants are getting the right amounts. Also be sure the timer waters in the morning to reduce loss to evaporation and prevent moisture from staying on plants overnight.

Water During the Early Parts of the Day; Avoid Watering When It Is Windy Early morning is generally better than dusk since it helps prevent the growth of fungus. Early watering and late watering also reduce water loss to evaporation. Watering early in the day is also the best defence against slugs and other garden pests. Try not to water when it’s windy: wind can blow sprinklers off target and speed evaporation. An automated watering system with a built-in moisture sensor can help ensure you’re only watering when necessary and at the most efficient time of day. If you’re using a timer, consider adding a rain or moisture sensor to avoid watering unnecessarily.

Add Organic Matter to Your Garden Beds Adding organic material to your soil will help increase its absorption and water retention. Areas that are already planted can be ‘top dressed’ with compost or organic matter every year. Turn a healthy dose of compost into new garden beds when preparing the soil for planting.

Harvest Rainwater for Watering Vegetable Beds Use rain barrels or a catchment system to capture valuable rainwater from your roof. Plants prefer untreated water, so your garden will be healthier while you cut your water bill.

Use a Soil Moisture Meter to Gauge When You Should Water Your Garden Avoid over- or under-watering your garden with a simple-to-use soil moisture meter . The meter quickly lets you know whether the soil is dry, so you only need to water when the plant actually needs it.

Control Weeds to Reduce Competition for Water in the Garden Weeds use water, too! If you don’t weed, the garden invaders will take up water meant for your plants. A good layer of mulch around your plants not only conserves soil moisture but helps keep weeds under control.

Lawns and Shrubs

Plant Drought-resistant Lawns, Shrubs and Plants If you are planting a new lawn, or overseeding an existing lawn, use drought-resistant grasses such as “Eco-Lawn” . Many beautiful shrubs and plants thrive with far less watering than other species. Replace herbaceous perennial borders with native plants.

Native plants will use less water and be more resistant to local plant diseases. Consider applying the principles of xeriscape for a low-maintenance, drought resistant yard. Plant slopes with plants that will retain water and help reduce runoff. Group plants according to their watering needs.

Put a Layer of Mulch Around Trees and Plants Mulch will slow evaporation of moisture while discouraging weed growth. Adding 2 – 4 inches of organic material such as compost or bark mulch will increase the ability of the soil to retain moisture. Press the mulch down around the drip line of each plant to form a slight depression, which will prevent or minimize water runoff. Learn more about different mulch materials and their best use.

Position Sprinklers Carefully Position your sprinklers so water lands on the lawn or garden, not on paved areas. Also, avoid watering on windy days.

Water Your Lawn Only When It Needs It A good way to see if your lawn needs watering is to step on the grass. If it springs back up when you move, it doesn’t need water. If it stays flat, the lawn is ready for watering. Letting the grass grow taller (to 3″) will also promote water retention in the soil.

Most lawns only need about 1″ of water each week. During dry spells, you can stop watering altogether and the lawn will go brown and dormant. Once cooler weather arrives, the morning dew and rainfall will bring the lawn back to its usual vigor. This may result in a brown summer lawn, but it saves a lot of water. You can also replace thirsty Kentucky bluegrass lawns with Eco-Lawn , a grass seed mix that lowers your lawn’s water needs by over 85%.

Deep-Soak Your Lawn When watering the lawn, do it long enough for the moisture to soak down to the roots where it will do the most good. A light sprinkling can evaporate quickly and tends to encourage shallow root systems. Put an empty tuna can on your lawn – when it’s full, you’ve watered about the right amount. Most lawns want about an inch of water per week, so note how much rain fell and add water accordingly. Visit our natural lawn care page for more information.

Use Efficient Watering Systems You can greatly reduce the amount of water used for shrubs, beds, and lawns by strategically placing soaker hoses installing a rain barrel water catchment system ; or installing a simple drip-irrigation system . For trees and woody shrubs, consider deep watering with slow-delivery irrigation like tree-ring soaker hose . Be sure to avoid over-watering plants and shrubs, since this can diminish plant health and cause yellowing of the leaves. When hand watering, use a variable spray nozzle for targeted watering.

Plant in ‘Hydro-Zones’ to Maximize Water Use Grouping plants with similar water needs means you won’t be wasting water on plants that don’t need it. Keep your water-wise and xeriscaped plants together, and do likewise with thirstier plants. Water only certain zones regularly, while watering drought-tolerant plantings less frequently.

Plant Trees in the Yard for Shade In addition to making your house cooler and storing carbon, adding shade trees can lessen the need for watering. By protecting plants and soil from the afternoon sun, shade trees help conserve water.

Water Conservation Summary

In 1990, 30 states in the US reported ‘water-stress’ conditions. In 2000, the number of states reporting water-stress rose to 40. In 2009, the number rose to 45. There is a worsening trend in water supply nationwide. Taking measures at home to conserve water not only saves you money, it also is of benefit to the greater community.

Saving water at home does not require any significant cost outlay. Although there are water-saving appliances and water conservation systems such as rain barrels, drip irrigation and on-demand water heaters which are more expensive, the bulk of water saving methods can be achieved at little cost.

By using water-saving features you can reduce your in-home water use by 35%. This means the average household, which uses 130,000 gallons per year, could save 44,00 gallons of water per year.

For example, 75% of water used indoors is in the bathroom, and 25% of this is for the toilet. The average toilet uses 4 gallons per flush (gpf). You can invest in a ULF (ultra-low flush) toilet which will use only 2 gpf. But you can also install a simple tank bank, costing about $2, which will save .8 gpf. This saves 40% of what you would save with the ULF toilet. Using simple methods like tank banks, low-flow showerheads and faucet aerators you can retrofit your home for under$50.

By using water-saving features you can reduce your in-home water use by 35%. This means the average household, which uses 130,000 gallons per year, could save 44,00 gallons of water per year. On a daily basis, the average household, using 350 gallons per day, could save 125 gallons of water per day. The average individual, currently using 70 gallons per day, could save 25 gallons of water per day.

When buying low-flow aerators, be sure to read the label for the actual ‘gpm’ (gallons per minute) rating. Often, the big box retailers promote “low-flow” which are rated at 2.5 gpm, which is at the top of the low-flow spectrum. This may be needed for the kitchen sink, but we find that a 1.5 gpm aerator works fine for the bathroom sink and most water outlets, delivering the same spray force in a comfortable, soft stream. Eartheasy’s online store carries a full range of low-flow aerators and showerheads.

Finally, it should be noted that installing low-flow aerators, showerheads, tank banks and other water-saving devices usually is a very simple operation which can be done by the homeowner and does not even require the use of tools. Water conservation at home is one of the easiest measures to put in place, and saving water should become part of everyday family practice.

Water means Life. Water is a prime natural resource. It is a basic need for humans and a precious asset that living beings have. Water is equally vital for the survival of the plant and animal kingdoms. Soil needs water for sustaining plants. The water cycle is essential for ecological balance too. Though a big portion of the Earth is covered with water, only a small portion of it can be used for various human activities. So we need to be judicious and rational, regarding the usage of water.

Why is water important for our bodies?

Water is important for our body for the following reasons.

Above 70% of our body contains water so it is pivotal for the human race to survive.

Water helps in regulating our body temperature.

Water helps in the digestion of solid food.

It also keeps our skin healthy and hydrated.

Water helps in excreting waste from our body through sweat, urination, and defecation. So replenishing the water in our body is essential to prevent dehydration.

Drinking water also helps in reducing calories and maintaining body weight because it can increase the rate of metabolism.

Water consumption lubricates the joints, spinal cord, and tissues.

Importance of Water

All living organisms, plants, animals, and human beings contain water. Almost 70% of our body is made up of water. Our body gets water from the liquids we drink and the food we eat. Nobody can survive without water for more than a week. All plants will die if they do not get water. This would lead to the death of all the animals that depend on plants for their food. So the existence of life would come to an end.

Role of Water In Life Processes

Water plays an important role in most of the life processes by acting as a solvent. The absorption of food in our body takes place in solution form with water as the solvent. Also, many waste products are excreted in the form of solutions through urine and perspiration.

Water helps in regulating our body temperature. In hot weather, we drink a lot of water. This maintains our body temperature. Also, water evaporates from the surface of our body as sweat. This takes away heat and cools the body.

Water is essential for plants to grow. Plants need water to prepare food. They also absorb dissolved nutrients from the soil through their roots.

Aquatic plants and animals use the nutrients and oxygen dissolved in water for their survival.

Uses of Water In Everyday Life

Water is used for drinking, washing, cooking, bathing, cleaning, in our day-to-day life.

It is used to generate electricity in hydroelectric power stations.

Water is used for irrigating fields and in the manufacture of various products.

Other Uses of Water

Water serves as a means of transportation for goods and people.

It provides a medium for recreational sports such as swimming, boating, and water skiing.

Water is also used to extinguish fires.

Importance of Oceans

Oceans are of immense use to man. They are useful in many ways, directly and indirectly. They not only play a significant role in the climate of adjoining countries but also serve mankind in many ways. They are a storehouse of several resources.

An ocean is a major source of water and forms a major part of the water cycle. Oceans contribute water vapor to the atmosphere and we get the same in the form of precipitation.

The oceans are the biggest storehouse of edible forms of marine food, fish being most important. In addition to food, sea animals provide other products like oil, glue, etc.

Oceans have enormous mineral and chemical wealth. A variety of dissolved salts like sodium chloride (common salt), magnesium chloride, and potassium chloride are found in plenty in the oceans.

Oil and gas are important fuels obtained from oceans.

Importance of Lakes and Rivers

Economic and industrial development

Water storage

Hydroelectric power generation

Agricultural purposes

Modern multipurpose dams

Source of food

Source of minerals

Tourist attractions and health resorts

Rivers provide fresh drinking water

Ports can be built on them as they form good natural harbors

Major Concerns

Although our planet Earth is covered with 71% percent of water and 29% of the land, the fast-growing contamination of water is affecting both humans as well as marine life. The unequal distribution of water on the Earth and its increasing demand due to the increasing population is becoming a concern for all.

Water pollution makes it difficult for marine animals to sustain themselves.

Covering over 71% of Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprising Hydrogen and Oxygen, life on Earth would be non-existent.

We are slowly but harming our planet at a very alarming rate.

Characteristics of a Good Essay.

It must be brief: As pointed out earlier, a good essay must be short, and also to the point. So, if students are writing an essay on the importance of water it must only deal with the water, and anything which does not directly serve the purpose must be excluded.

Must cover the whole topic: Though it may seem a little contradicting to the first point, what is meant by covering the whole topic is that the maximum number of aspects dealing with the importance of water must be covered in this essay. For instance, water is important for all living organisms and not just humans, and so the same has to be covered in one or the other way in the essay on the importance of the water.

Must be to the point: The essay must remain true to the central idea of the topic, which is the importance of water in this case. Hence, almost all the sentences written in the essay must serve the main topic in one or another way. And also, writing should not be vague or ambiguous, or illogical.

Human beings should realize how important and precious water is. At the individual level, you can be more responsible and avoid wasting water so that our future generation can make the best use of this natural resource abundantly.

Why Is Water So Important? Here’s What You Need to Know

How water works in your body, how much water do you need, how to stay hydrated.

Water is a major component of your body, accounting for 50–60% of your total weight. It is vital for many important body functions, from flushing out waste to lubricating your joints.

Your body constantly loses water throughout the day through urinating, sweating, and breathing. You should consume enough water from foods and beverages daily to prevent dehydration .

This article covers research-backed reasons why your body needs water and how much you need each day.

Klaus Vedfelt / Getty Images

All body cells, organs, and tissues require water to function. Generally, a person can only survive without water for a few days.

It Maintains a Normal Body Temperature

Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat).

When the body becomes too hot, it loses water through sweat . The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.

If a person becomes dehydrated, they can't produce enough sweat to cool their body. This can cause the body's temperature to reach dangerous levels, leading to heat stroke .

Avoid dehydration by drinking plenty of water if you're working outside or sweating more than usual.

It Protects Your Joints, Spinal Cord, and Other Tissues

Water acts as a lubricant in the mouth (through saliva ) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid , which lubricates, cushions, and protects the joints.

Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It Transports Nutrients and Gets Rid of Waste

As a major component of blood, water helps transport nutrients and oxygen to cells throughout the body. Water also helps carry waste from the body for excretion through perspiration, urination, and bowel movements.

The kidneys need water to effectively filter waste from the blood and flush it from the body as urine. Staying adequately hydrated helps prevent kidney stones and urinary tract infections (UTIs) , which can harm the kidneys.

Prevents Dehydration

Drinking water daily can help prevent dehydration, a condition that occurs when you lose more fluids than you absorb.

Early signs of dehydration include:

Feeling thirsty
Dark-colored urine
Urinating less than usual

Because water is involved in so many body functions, dehydration can eventually cause life-threatening symptoms, including:

Rapid breathing
Rapid heartbeat
Inability to urinate

People who exercise in the heat, work outdoors, or have certain health conditions that cause them to urinate or sweat more than usual are at a greater risk of dehydration.

It Aids Digestion

Your saliva is primarily made up of water. Saliva is a digestive juice that moistens food, allowing it to move easily through the esophagus into your stomach. Saliva also contains enzymes that help break down starches in food.

As the digestive process continues, water helps break down food, allowing your body to absorb nutrients. Water also makes bowel movements easier.

It Protects Against Chronic Illness and Boosts Longevity

Adequate hydration is linked to healthy aging and longevity. One potential reason for this is that decreased water intake can lead to higher sodium concentrations in the blood, which raises the risk of chronic disease.

Studies suggest that adults who stay hydrated are healthier and less likely to develop chronic diseases, including heart and lung disease . Well-hydrated adults also seem to live longer than adults who don't consume enough fluids.

It Improves Mood and Cognitive Function

Dehydration may cause fatigue and confusion and may be linked to symptoms of anger and depression. In a small study, it was linked to poor cognitive function, potentially affecting attention span and working memory.

One study of young adults looked at the effects of water on cognitive performance and mood after 12 hours of water restriction. Researchers found that 200 milliliters of water improved thirst, anger, fatigue, and overall mood. However, 500 milliliters was optimal, improving mood and cognitive performance.

The amount of water you need depends on several factors, including age, sex, activity level, and health status.

For healthy individuals, the adequate daily water intake is around 11.5 cups for women and about 15.5 cups for men. This includes fluids consumed from all foods and beverages.

Experts estimate that most people get around 20% of their daily water intake from food. This means women should drink about 9 cups of fluid daily, while men should aim for 13 cups to maintain adequate hydration.

People who live in warmer climates, are more physically active, or are experiencing an illness that causes fever and/or diarrhea or vomiting have increased fluid needs.

One easy way to see if you are properly hydrated is to check the color of your urine. If you are drinking enough water, your urine will be pale yellow. If it is dark, you may need to increase your consumption.

Individuals with heart failure or kidney disease may need to limit their fluid intake.

Can You Drink Too Much Water?

Drinking too much water can lead to water intoxication or overhydration, which occurs when the kidneys cannot flush out excess water. This can cause a medical emergency due to decreased sodium concentrations in the blood ( hyponatremia ). To avoid water intoxication, do not drink more than 48 ounces, or six cups, per hour.

If you find it challenging to stay hydrated, here are some helpful tips to keep in mind:

Keep a reusable water bottle with you and refill it throughout the day
Choose water or sparkling water instead of sugary beverages
When you feel thirsty, drink water
Change things up by squeezing fresh lemon or lime into your water or adding a few berries or cucumber slices
Snack on water-rich fruits and vegetables , including watermelon, cantaloupe, lettuce, and celery, throughout the day
Keep track of your water intake by using a water tracker app
Drink water with all meals

Water is vital for your health. It is necessary for temperature regulation, digestion, nutrient absorption, and body waste removal. Drinking water daily can prevent dehydration, a condition that can cause mood and memory problems, constipation, and kidney stones.

People who work in high temperatures, exercise at high intensities, or are sick are at a greater risk of dehydration. Talk to a healthcare provider or registered dietitian to determine the right amount of water for you.

500+ words essay on importance of water.

Water is the basic necessity for the functioning of all life forms that exist on earth . It is safe to say that water is the reason behind earth being the only planet to support life. This universal solvent is one of the major resources we have on this planet . It is impossible for life to function without water. After all, it makes for almost 70% of the earth.

However, despite its vast abundance, water is very much limited. It is a non-renewable resource . In addition, we need to realize the fact that although there is an abundance of water, not all of it is safe to consume. We derive some very essential uses from the water on a daily basis.

Significance of water

If we talk about our personal lives, water is the foundation of our existence. The human body needs water for the day to day survival. We may be able to survive without any food for a whole week but without water, we won’t even survive for 3 days. Moreover, our body itself comprises of 70% water. This, in turn, helps our body to function normally.

Thus, the lack of sufficient water or consumption of contaminated water can cause serious health problems for humans. Therefore, the amount and quality of water which we consume is essential for our physical health plus fitness.

Further, our daily activities are incomplete without water. Whether we talk about getting up in the morning to brush or cooking our food, it is equally important. This domestic use of water makes us very dependent on this transparent chemical.

In addition, on a large scale, the industries consume a lot of water. They need water for almost every step of their process. It essential for the production of the goods we use every day.

If we look beyond human uses, we will realize how water plays a major role in every living beings life. It is the home of aquatic animals. From a tiny insect to a whale, every organism needs water to survive.

Therefore, we see how not only human beings but plants and animals too require water. The earth depends on water to function. We cannot be selfish and use it up for our uses without caring about the environment.

A world without water

Water is not only required for our survival but for a healthy and happy life as well. Everyone has seen the scenario of water-deprived countries like Africa, where citizens are leading a miserable life. It is time for everyone to wake up and realize the urgency of conserving water.

In other words, a world without water would make the human race impossible to last. The same can be said for all the animals and plants. In fact, the whole earth will suffer without water.

Firstly, the greenery will soon diminish. When earth won’t get water, all the vegetation will die and turn into barren land. The occurrence of different seasons will soon cease. The earth will be caught in one big endless summer.

Furthermore, the home of aquatic animals will be taken from them. That means no fishes and whales for us to see. Most importantly, all forms of living organisms will go extinct if we do not conserve water right away.

In conclusion, unnecessary usage of water must be stopped at once. Every single person must work to conserve water and restore the balance. If not, we all know what the consequences are going to be.

Introduction

Water is really one of the most important things we need to live and grow. However, it is also known as the universal solvent. Thinking of life is directly proportional to saving water.

Importance of Water

Water is essential to the survival of every living thing on this earth. Water is essential for many things, like drinking, cooking, washing, farming, and so on. For maintaining a good health, we need pure and fresh water. The industrial sector needs water a lot. Big dams store water so that it can be used to make electricity for homes, businesses, and other uses. It helps keep your body temperature stable, helps your body digest food, keeps your skin healthy, and can even help you lose weight.

Reasons for Water Shortage

With more industrial and scientific progress, this valuable resource is unfortunately, becoming less available. It is thought that 3 out of 5 people on the planet do not have access to safe drinking water or proper sanitation, which causes illness and death every day. The water is getting dirty because trash is being dumped into the reservoirs. If people don’t use water well, there may not be enough clean water in the future. It is very important to save water in order to save lives.

Water is a gift from nature that people have used to support their lives and make progress and development. It has never been more important to the world’s people than it is today. Water needs to be used in a way that won’t harm the next generation. So, it’s important to save water and use it in the right way.

Long Essay on Water (500 Words)

Our planet has a lot of water. 70% of the surface of our planet is covered with water. However, only 3% of all water is fresh water. Out of which, two-thirds are frozen in glaciers or in other places where we can’t use it. Water is one of the most valuable things in nature. Throughout history, water has had a big effect on people’s lives in many ways.

Water: The Precious Resource

Only Earth has water, which is the main thing that makes life possible. There are many sources of water on Earth, such as the ocean, rivers, lakes, ponds, etc. Organisms can survive without food, but not without water. Apart from drinking water, we can use it for many other things. It helps to get rid of waste and toxins and helps prevent diseases like kidney, heart, and liver disease. Different plants need different amounts of water. Even animals need water to live.

Uses of Water

Water can be used for many other things like cooking, cleaning, bathing, and drinking. It can be used as a way to use for transportation. Besides this, water is also used for things like washing cars, building homes, putting out fires, etc. Electricity is also produced with the help of water. Irrigation purposes also require huge amount of water. These are used in the business world to make the economy grow. Water is also used for fun things like swimming, surfing, boating, water parks, and many others.

Need to Save Water

Many of the water sources that keep ecosystems healthy are under stress. Because of too much use, rivers, lakes, and aquifers are drying up and getting too dirty to use. Due to more people living in cities, production and manufacturing units need more and more water. Wastes from factories and other businesses are getting into the water sources. In recent years, there has been a lack of water. It is important to protect the sources of freshwater that can be used for drinking.

How to Save Water

Reducing water pollution is an important step toward making clean water easier to get. Using new technologies like wastewater recycling, nanofiltration, solar and UV water filtration, and rainwater harvesting systems can also help a lot with the problem of water scarcity.

One of the easiest and best ways to save water is to collect rainwater and put it back into the ground. You can save water at home in many ways, such as by taking shorter showers and reusing water. To save water, wash your clothes and dishes in a machine that uses less power. Government should take necessary steps to prevent water wastage.

Water is a basic need that everyone should be able to get. We can’t make water, so it’s a valuable resource that we should all use with care. Without water, nothing can live. By saving water, we can make sure that our children and grandchildren will live on this planet and be safe and healthy.

Essay on Save Water (1000+ words) Simple Ways To Conserve

Saving water is vital to our planet. We must all do our part in conserving water because it is a finite resource. Water should be consumed only when necessary and should be saved for activities that require large quantities of water.

Water is the most important natural resource on the planet. The water cycle ensures that water is constantly being renewed, so it can be used again and again without ever being used up.

The challenge for individuals is to use water wisely, conserve water, and reuse it in ways that won’t endanger the environment.

Some countries have wars over access to fresh water while others have drought problems. The bottom line is that there are many reasons why water scarcity is a problem around the globe.

Here are some ways to reduce your water consumption.

The importance of saving water

What does water do for us? Water is the most important resource. Without it, humans can’t survive. Water is found in nature, but over the course of time, it is collected, purified, and used to create life.

Water is an essential element to humans, but it is limited in quantity. The more water we use, the more we need to conserve. Water is used for drinking, food, personal hygiene and laundry.

Each of these actions uses more water than the previous one. Each minute, 1/3 of the world’s population is using up more than 1/2 million liters of water. And the average person uses over 100 liters of water a day.

There is still a lot of room to increase water conservation rates, but in order to do so, we have to start conserving.

Get creative with your lawn

Many of the methods require minimal amounts of water, and only require your help to understand and implement. Remember, your lawn still needs water, it’s still a living thing.

You can expect it to turn brown if it’s too dry, just like every other living thing! More often mowing your lawn at a longer length is a more water-efficient choice, than mowing it shorter. Longer grass takes more time to dry out, so it can be watered less frequently. Use a zero-turn mower or a trimmer with a narrow blade.

Save water in the shower

Water your clothes less often. Use water-efficient showerheads and low-flow showerheads. Buy towels made from towels grown without harsh chemicals, which soak up less water.

Use a reverse osmosis showerhead to remove salts and contaminants from the water. Empty wastebaskets more often. Not leaving the water running means you can help save water.

Use less water for cooking

Cooking is one of the biggest water users in your home. Think about how much time you spend cooking, and how much water you use.

It doesn’t take long before you are using more water than necessary for just one meal. Use appliances with good energy ratings to reduce water consumption.

For example, dishwashers use nearly 3% of the total water use in a typical home. Many dishwashers available today have the energy ratings for efficient operation.

Create an optimal water usage routine. We need to think about the types of water you use inside the house, which is something that is very important.

Conserve water outdoors

Take showers instead of baths. Many people only do one or the other. Ditch the fancy soaps and opt for a small amount of shampoo and conditioner in a small bowl. Shaving your body, legs and underarms should also be done in showers and not by hand.

What is the point of cleaning the car and putting it outside in the rain if you’re not going to clean it? Car washing is a job that must be done regularly, even if it rains. Many people are unaware that rain can wash away some of the dirt on your car.

Water-wise gardening techniques

One of the most common ways to conserve water is by planting water-wise flowers. These are flowers that can handle watering on a regular basis throughout the summer, but dry up for the winter.

Other water-wise gardening techniques include planting turf plants, which do not require water when the ground is frozen.

Using drip irrigation for regular irrigation. Frequently checking the weather forecast to decide when to water your plants.

Rain barrels are simple, yet effective, water-conserving devices. They can be attached to a hose, and they allow you to use rainwater as your regular water source, and it can be used for various purposes.

Most of them are an added expense, but many families find that they save significant amounts of water.

Choose the right toilet for your home

Poor water management can have a detrimental effect on the quality of life of your family, particularly if you have children. This is why your toilets should be appropriate for your home and your lifestyle.

A solid ceramic flush toilet is the most efficient for an efficient and comfortable flush, but it is not suitable for indoor use and is a fire hazard.

As a general rule, a tiled or porcelain flush will hold at least 25 litres of water, which is a lot more than an external clog can hold.

These are the types of toilets most common in apartments and houses. Apart from your kitchen and bathroom, you also need to remember to get a variety of toilets to cater to different needs.

Some simple ways to save water

Run dishwashers in the evening to reduce dishwasher water use.
Reduce showering to three minutes.
Use low-flow showerheads.
Run water through faucets to remove soap, rinse hands and/or face, and clean off pets.
Bring your water to a rolling boil for 1 minute to kill harmful bacteria.
Use hand sanitizer before and after cleaning or touching anything that could possibly touch your eyes, mouth or nose.
Turn off the faucet while brushing your teeth, or using a toothbrush, and hand sanitizer to remove plaque.
Turn off the faucet while brushing your teeth, or using a toothbrush, and soap and water to rinse your toothbrush.
Turn off the faucet while brushing your teeth, or using a toothbrush, and soap and water to rinse your mouth.

Install a rain barrel on your property or landscape

Improve landscaping with native plants, and shrubs Check the water table in your area. Use rain barrels to capture and use rainwater. Reuse water from other household chores (bathtub water, for instance).

Check for underground water leaks. Make sure water plants are not getting too much or too little water Increase water efficiency with aeration and misters.

Repair leaks in the house and leaks around irrigation systems. Include drinking water conservation tips in your homeowner’s policy.

Final Words

We all know that water is the elixir of life, but too often we take it for granted. It’s easy to overlook how much water is used for everything from cooking our food, to washing our clothes, and taking care of our children.

It seems like every day we are being reminded of the importance of water in our lives. But what can you do? You’re not the only one who needs clean water. All over the world people are struggling with where to find water when they need it most.

Saving Water and Methods of Its Protection Research Paper

Introduction, water scarcity, industrial water protection and conservation, domestic water protection and conservation measures, forced water conservation, discussion and conclusion, reference list.

Every form of life depends on water for existence. Water is also critical for most industrial processes. However, misuse and pollution of water are making it a very scarce commodity although most of the world population does not realize this. This paper describes water scarcity, factors behind the scarcity and the possible methods of protecting and conserving it.

At an industrial level, a good water management plan (WMP) is mandatory. Apart from saving water, the good WMP benefits the industry in various other ways. These are described in the paper. It also considers various methods of saving water at home and the possibility of forced water conservation in cases where consumers are ignorant.

What is water? How and why do we need to conserve it? These are very important questions when considering sustainability of life in the future. Most people especially in the developed world do not realize that sustainability of life in the future is at stake if measures to conserve water are not implemented.

This is because through out their lives, these people have had readily available fresh water (Cheng, 2010). Their taps and showers never run out of water, the water closets always flush and even when they need ice, the refrigerator has more than enough. The only people who realize that water is scarce are those from arid and semiarid regions where getting a cup of clean drinking water counts as one of their greatest challenge.

In the developing countries of Africa and the Middle East, women from some places walk for six kilometers a day just to fetch water. Even in their cities, water crisis is not a new thing. This has not been felt in the developed countries because of the well-established infrastructure, which is absent in the developing countries. Due to this, the issue of water scarcity is assumed to only affect the developing countries.

However, this is not the case and Live Earth CEO has warned that in 20-25 years time, there will be a disaster in developed countries (Mueller, 2010). There is therefore a dire need to protect and conserve water in our daily domestic and industrial activities.

Water is a unique compound. It exists naturally in three physical states namely: solid, liquid and gas unlike many other compounds.It is vital for sustenance of life; it transports nutrients and oxygen to cells, normalizes body temperature, regulates Earth’s temperature, removes wastes, protects tissue, and many other functions (“importance of water,” n.d.).

Without water, standard animals would only survive for a few days.At an industrial level, all manufacturing and processing companies require water somewhere along their production lines.Water is therefore important not only for existence of life, but also for economic activities.It needs to be protected and conserved.

In order to show effectively the importance of conserving water, it is imperative to show the logical reasons for doing so. Since it is a known fact that 80% of the earth’s surface is covered by water, someone may ask how then water can be scarce. To answer this question, water is scarce because only less than 1% of this surface water is fresh water (“The water cycle,” n.d.).

Almost all of our daily needs such as drinking, cooking, irrigation, manufacturing and many others require this fresh water. Apart from the surface water, there is the ground water. This water is also available for use but over the years, the water table has been decreasing day by day. Boreholes dry up and deeper ones need to be drilled.

Another problem with availability of water is water pollution. Although Earth’s processes recycle water, its pollution makes it unavailable for future use. Factory discharges, pesticides and herbicides, sewage waste, detergents and all other chemicals that we use on the surface affects the natural water sources. Pollution is therefore acting as one of the major reasons of scarcity in portable water. Measures to protect and conserve water can be applied at domestic and industrial level.

Industries should also strive to conserve water. To do this, they need a water management plan (WMP) which is effective. For the water management plan to be effective, it must incorporate both systems and technical approaches (Mohan, 2007). This is because incorporating both systems and technical approaches ensures that water management is sustainable.

That is, the plan will effectively manage the water usage at the current state of the company as well as in the future. The change in management priorities or departure of a champion for the plan does not jeopardize the WMP. Therefore, an effective WMP ensures continued improvement in water conservation. All companies that are planning to conserve water must have an effective WMP.

Traditional water management systems only incorporated the technical approach and sustainability was a problem. Mohan (2007) describes the characteristics of a good WMP to be leadership, accountability, efficient water usage, minimized pollution, addressing behavioral changes in water usage, driving development of data collection and reporting of water usage, specifying the benefits and costs of the system to the company and driving changes in how the company interacts with suppliers.

By ensuring that the water management plan of the company meets these characteristics, sustainable water management by the company is achieved. The company also achieves other benefits. It saves costs, aligns water conservation with corporate strategy, good public relation and citation for obtaining subsidies among others. The plan also has the overall effect of minimizing water shortage.

At home, every individual can contribute at protecting and conserving water. If everybody is made aware of the importance of conserving water, the world’s population may safeguard its future and that of the future generations.

One of the areas in which people can save water is through minimizing the quantity of water spent every day. People use water without caring if there will be more tomorrow. They just know that if there is no water, they will complain to the city council and the problem will be solved. This is especially the case if the families can afford the clear the water bills.

People misuse the water because they can pay for it. They spend too much time in the shower, leave the taps running unnecessarily and excessively water their lawns. These are just a few examples of some of the ways people use excessive water in circumstances that would require less water. By making people aware of the effect their activities have on water availability, some wasted water will be conserved.

Apart from conserving water, individuals may also protect water sources from pollution. Use of environmental friendly detergents and other household chemicals will have a positive impact on minimizing the level of water pollution. By minimizing water pollution, the costs involved in treatment and purification of water will be used to implement other infrastructure in water management.

Leaving the option of conserving water to individual citizens may not be very effective since some of them may not care much. The authorities involved in provision of water should put in place measures that force the consumers to conserve water. In Los Angeles, the city’s department of water and power has implemented several restrictive measures to cub water wastage.

Lawn sprinklers in the region are not permitted between 9.00am and 4.00pm (Welch, 2009). This ensures minimum water loss through evaporation. In addition to this, the sprinklers are only permitted twice a week a week (Welch, 2009). The result of these restrictions is that water consumption by single-family homes decreased by over 23 percent.

To be able to observe these restrictions, Los Angeles residents had to change the type of vegetation they planted on their compounds. They replaced grass that requires a lot of water with low water native plants like rosemary and synthetic grass. These measures by the city council were effective in controlling wastage of water.

It is worth noting that the city council determined the most water wasting activities performed by residents of Los Angeles and restricted them. This can also be done in other cities. If residents of Los Angeles, which receives very little rainfall in a year, can save water, residents of other places can save water too

Ensuring water conservation is a challenging task. It has many challenges especially since it mainly depends on people’s perception and willingness to change. To change people’s perception and habits, intensive awareness campaigns are needed and this requires a lot of investment.

With few bodies ready to support such campaigns, it is still not possible to reach every individual and change their water usage habits. At the industrial level, investment is also needed to implement WMPs. Most corporate organizations are not willing to make the step especially those focused on only maximizing their profits. These limitations therefore call for forced water conservation by authorities, which is not sometimes possible due to lack of such laws in many places.

Water is vital for existence of life. It is also important for economic activities carried out by man. The amount of water available on Earth is not enough to meet all its requirements. Further more, with the current excessive waste of fresh water and pollution, the life of future generations is at stake. If protection and conservation of water is not done, there will be a disaster in the coming few decades. The conservation measures are needed at both domestic and industrial levels.

At the domestic level, awareness is needed since most people in developed countries do not realize the importance of conserving water. Forced water conservation is even needed in some cases. At an industrial level, all companies should develop and implement an effective water management plan (WMP) that ensures sustainable water management.

Water, the universal solvent, is one of the most essential elements to life on Earth. Constituting approximately 71% of our planet’s surface and 60% of the human body, the importance of water cannot be overstated.

Biological Significance

Water plays a critical role in biological processes. It is the medium for various enzymatic and chemical reactions, aids in the transportation of nutrients, and provides the cellular structure necessary for life. Its high heat capacity enables the regulation of body temperature, while its polarity and cohesion contribute to its role as an excellent solvent.

Ecological Importance

Ecosystems heavily rely on water. Aquatic ecosystems provide a habitat for a myriad of species, while terrestrial biomes are shaped by the availability and distribution of water. Water cycles, including evaporation, condensation, and precipitation, help in the distribution of heat around the globe, influencing climate and weather patterns.

Economic and Social Value

Water is fundamental to various industries, such as agriculture, hydroelectric power, and manufacturing. It is also vital for domestic use, including drinking, cooking, cleaning, and sanitation. Access to clean water is a significant social issue, with water scarcity affecting billions worldwide.

In conclusion, water is an indispensable resource, playing a pivotal role in biological, ecological, economic, and social aspects of life.

500 Words Essay on Importance of Water

Water, the most abundant and essential compound on Earth, serves as the lifeblood of the planet, supporting the survival and development of all known forms of life. It is a critical resource, not just for individual survival, but also for the functioning of ecosystems, agriculture, industry, and even culture and religion.

The Role of Water in Life Processes

Water plays an indispensable role in the fundamental life processes. It acts as a solvent, making possible the transport of nutrients, hormones, and waste products within and between cells. The unique properties of water, such as its capacity to absorb significant amounts of heat without changing temperature, are vital for temperature regulation in organisms and the environment.

Water and Ecosystems

Ecosystems, whether terrestrial or aquatic, are intricately tied to water. It shapes the landscape, determines the species that inhabit an area, and influences the complex interactions within ecosystems. Wetlands, for instance, serve as biodiversity hotspots, providing habitat for a wide variety of species. They also act as natural water filters, improving water quality by trapping pollutants and sediments.

Water in Agriculture and Industry

Water is the cornerstone of agriculture, necessary for the cultivation of crops and rearing of livestock. Without a steady supply of water, food security can be significantly compromised. Industries, too, rely heavily on water for various processes, including cooling, cleaning, and as a raw material.

Socio-cultural Significance of Water

Beyond its physical and economic importance, water holds profound socio-cultural significance. Many cultures and religions attribute sacred qualities to water, using it in ceremonies and rituals. It also plays a central role in social organization, with water bodies often serving as communal gathering spots.

Water Scarcity and Conservation

Despite its abundance, water scarcity is a pressing issue in many parts of the world, exacerbated by climate change, pollution, and overuse. This scarcity not only threatens individual survival and health but also has far-reaching implications for biodiversity, food security, and social stability. Therefore, water conservation strategies, from individual actions to policy interventions, are crucial to ensure the sustainable use of this invaluable resource.

In conclusion, water is a critical resource that underpins life, supports economic activities, and holds deep cultural significance. However, the growing threat of water scarcity necessitates urgent action for its conservation. By understanding and appreciating the importance of water, we can foster a more sustainable and respectful relationship with this life-sustaining resource.

Short Essay on Water in 100 Words

Every living being on the earth needs some basic things for its survival. It includes food, water, shelter, and money as well for humans. Water is by far the principal need of living beings. About two-third part of the earth is covered with water.

Water is available in several forms on earth. Some amount is frozen in glaciers, while the larger amount of water is salty. Fresh water on earth is very little. We need water for every purpose. Drinking, cooking, bathing, washing are the basic needs, while water is also used by bigger industries to run their machines. Water is an important source of electricity. So, being the most valuable resource water must never be wasted.

Short Essay on Water in 200 Words

Water is the most significant resource among everything that humans and animals can receive. Water helps a living being to live for longer days, even when food is scarce. It is one of the most beautiful gifts of nature. Water has enormous benefits and is the life of the earth. Its medicinal properties cure several ailments in our bodies. Without it, we cannot imagine living a second on earth. The world will be a huge desert if the water on earth is destroyed.

Our earth is unique in its creation. About two-third part of it is covered with water, while the rest of it is land. If we take a deeper study, then a major part of the water is either frozen as glaciers or is present in the oceans as saltwater. The reserve of fresh water on earth is a limited amount. It can exhaust at any moment. Hence we must spend water wisely. We need water for drinking, bathing, washing clothes and utensils, cooking, cultivating, etc.

Big industries require lots of water to run their machines. Today due to the scarcity of coal, hydroelectricity is the new way of generating electrical power. This process requires huge amounts of water. In several ways, water is our saviour. It is the beauty of nature as a wonderful waterfall or a stream, and also the help to a thirsty person.

Short Essay on Water in 400 Words

Water is the basic strength behind all life forces on earth. It is the necessity of every life and is the biggest shelter for us to survive. If there is no water suddenly on earth, then it will only be a lifeless planet filled with dust and stone.

The green earth will become a long stretch of a desert without this component. Water forms about two-thirds of the earth, while only one-third is given for the land. Yet how much greater the amount of water on earth be, the availability of fresh water on earth is the minimum.

A large amount of water is left unused. It is either frozen as glaciers or is present as salty ocean water. This water cannot be applied for regular usage. So we must understand the wise utilization of water. It is a scanty but most important resource. So only its proper utilization can make it sufficient.

Water is the source of all activities in our lives. From the olden days, human beings have always tried to live near water bodies. Because those places are fertile for cultivation. A vast desert-like Egypt also survives because of the river Nile. The Ganges in India is not only a water body but one of the most sacred rivers in the world. The most important use of water is in agriculture.

Every plant needs it to grow. If crops do not receive adequate water, then they will be stunted. We use water for drinking, cooking, bathing, washing. A living body needs lots of water intake. Insufficient water intake can result in lots of ailments. Water is beneficial for this medical property. Besides these, all industries need water for producing electricity and running the turbines. Water is the potential of civilization. A civilization operates because of the availability of water

But at present, we are observing the pollution of water bodies. It is dangerous for all living beings to survive if all water sources are contaminated. Polluted water is a threat to the earth. Households, industries, insufficient cleanliness, lack of awareness, all are enough to increase pollution in several degrees. With increased consumption of water, it is being equally polluted. Thus many aquatic plants and animals, humans, other land animals are regularly dying after intaking the dirty water.

This is harming our ecosystem. So we must preserve freshwater. It is important and is available in little amount. Clean water can exhaust at any moment. It is our duty even to preserve the rainwater and use it. Every drop of water means life. A correct utility of it is the best way.

So, that was all about writing short essays on Water. In this session above, I have adopted a simplistic approach to writing all these essays for a better understanding of all kinds of students.
