Students study the effects of water erosion on soil by gathering and analyzing data during an experiment. They decide on appropriate units of measurement to apply in problem solving.

Sixth graders investigate erosion. In this erosion lesson, 6th graders explore how farming changes the environment. Students construct an erosion model and research ways to protect the soil from excess mud generated by farming.

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Fifth graders brainstorm a list of ways the Earth's surface can change. As a class, they are introduced to the concepts of erosion and weathering and discover how wind and water cause changes to the surface of the Earth. To end the...
