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...

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

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...

In this environmental science fair project, students will build models of fields prepared by plow-based and no-till methods, and see which ones are best at retaining soil moisture and preventing surface runoff.

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.
