Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their...

Students build a model to learn about the cycle of erosion and deposition by water and wind which deposits layer upon layer of rock, soil, and organic material to the surface.
