Point- vs. Non-point Pollution

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Investigate the different types of pollution that storm drain runoff carries into oceans, lakes, rivers, and streams with this class demonstration. Using an aquarium and an assortment of everyday items that contaminants like motor oil,...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson is meant...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

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 shuttles, young...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

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...

The Science of Water Teacher's Guide provides a number of inquiry-based activities for grades 3-5 (although it can be expanded for other grades). The guide contains science lessons that enable students to explore water, behavior of...
