In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.
