How to Stop Erosion

This lesson has 2 parts! First, you’ll learn about rain, roots, and runoff, and set up an experiment to see if plants can help prevent erosion. Then, you’ll test the experiment, learn more about erosion, and engineer a man-made model that might be able to help prevent erosion too!
