Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

An introductory lesson to a unit on water pollution, young environmentalists are asked to brainstorm examples of pollutants in water. This lesson will help develop a sense of what water pollution is and where the pollutants come from.

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

Water, water, everywhere, but not a drop to drink—until we clean it, of course! Scholars design a filtration device that removes pollutants from water. The goal is to have the water come out as clean as possible from the device. How...

What's the point in saving water? Surprisingly water isn't a forever resource because it is a natural resource. Here, young water conservationists hunt for 23 wise water users and water wasters by clicking on the people in the...

Having a clean, reliable source of drinking water is essential for any community, but in many cases this is easier said than done. Engage young environmentalists in exploring the five factors affecting vulnerability of a groundwater...

Written as field trip preparation to Gateway National Recreation Area, this resource is also appropriate for any class that is studying the impact of human activity on the environment. During the first activity, learners identify...

Students see that ecosystems provide services to people that are essential to life as we know it. Reporters (drops of water) could interview the trees and soil in the surrounding ecosystems for news stories on how they helped keep the...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.
