Understanding whether water is clean or polluted requires more than just what the naked eye can see and therefore gives educators like you the opportunity to dive into chemistry with students!

In this lesson students will learn about the way pollutants are introduced into the water cycle and how these pollutants can impact ecosystems and human health. They will then learn how to perform water quality testing on several water samples, identifying the sources of contamination. Students will also learn how green space, specifically street trees in urban areas can be used to reduce contamination events in local ecosystems.
