When Rain Hits the Land
What is groundwater? What is runoff? How are they different? How does water cause erosion? Why is water absorption important?
Students will be able to identify what land surfaces cause run off and which allow water to soak into the ground. Students will learn why it is important that rain water be allowed to percolate into the soil, and what happens when it becomes runoff instead.
Students will be conducting “percolation” tests around the schoolyard by poring water into a can on top of different land surfaces and timing how long it takes for the water to percolate through.
