From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Fifth graders study the impact of human activity on water quality and on the ecosystems of Earth. After a discussion on the various ways that water can be polluted, groups of youngsters get together to figure out the best way to clean a...

Here is a fine lesson for fifth graders that will give them an idea of the variety of impacts that human-introduced pollutants have on the environment. After an initial class discussion and teacher-led demonstration, pupils brainstorm...

Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...

Water is one of the most precious resources on the earth. Explore water conservation, the importance of natural resources, and how water is used throughout the globe. Two complete activities along with discussion questions are used to...

Examine water as a scarce natural resource instead of taking it for granted. Middle schoolers identify the traits of potable water, and research local water sources to determine if they are impaired or not.

Middle schoolers name 3-5 aesthetic values of the Potomac River. They state the importance of water in their own words. Students describe what Earth Day is and why it is important. They list 5-7 ways that they can help minimize water...

Students experience and participate in "Riding the Water Cycle" with this activity. They explore, analyze and study the role of reservoirs in maintaining a reliable supply of drinking water. Each student constructs a model of a reservoir.

Students compare land to water ratio on our planet, list sources of drinking water, list steps in cleaning water in treatment plant, describe natural filtering process, and explain danger of not testing drinking water from private wells.

Fifth graders investigate the how water becomes polluted and how it effects the environment, animals, and humans. They watch a video and conduct experiments.

Students examine a globe to locate the bodies of water present and create a representation of those bodies of water for further exploration of the concept. Extensions of their observations are made at school, home, and the community.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

An excellent instructional activity on the water cycle! In it, learners should gain a general understanding of the water cycle, along with how water first falls as precipitation, then ends up coming out of our faucets. This instructional...

Students create an all-natural water filtration system. In this lesson on natural water filtration, students build upon prior knowledge to build a filtration unit made of plants, soils, sand, pebbles and rocks that can purify...

Students examine where water is found in the world, how we use it, and the various forms it takes. They observe the refraction of light through a prism, record the day and night sky over a week's time, and create a topographic model of...

Learners build a water filtration system. In this water quality lesson, students work in groups to construct water filtration units that can purify contaminated water. This lesson is part of a larger unit on water quality.

Students examine water samples assess the quality of each sample by examining the color/clarity, smell, pH, etc. of each Then they filter the water samples once and assess water quality a second time. finally they filter the samples a...

Students explore water. In this water absorbency lesson, students experiment with different items to see if they absorb water. Students record their findings on a data sheet. Students then try making music with drinking glasses...

Young scholars learn about the history of Indiana's water and understand how easily pollution can contaminate the water supply. They also learn how little fresh water we have and how important it is to protect it.

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this lesson is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions. They...

Students investigate water use and what happens at a water treatment plant. They define and discuss key vocabulary terms, view a diagram of a water treatment plant, and conduct an experiment that simulates the water filtration process.

Fifth graders observe and record what happens when household products are added to a tank of water to depict water pollution. They brainstorm ideas of how to clean the contaminate out of the water before watching demonstrations of...

Second graders create their own water treatment system. In this water treatment lesson, 2nd graders create the water treatment system and record how it works. Students list materials they used and write about what they saw. Students then...
