In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
