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 astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

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.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.
