Pollution in Our Watershed

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from pesticides used in agriculture. This activity is great way for learners to visualize how pollution can contaminate distant lands by getting into the water cycle and then can be carried to the nearby ecosystems. This lesson includes background information, wrap up questions, and is standards-based. [Activity is publicly available through a web crawler capture on Archive.org.]
