Shake and Break

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river. Learners put "stones" made of plaster of paris into a plastic container filled with water and shake the container for several minutes. They then compare the shapes of the rocks before and after shaking, and discuss how natural weathering of stones happens. The lesson plan includes handouts, background information, and suggested extension activities.
