Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

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.

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

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.
