Rocking Changes

Source Institutions

Add to list Go to activity
In this earth science activity, learners conduct a series of short experiments to explore how rocks change. Learners will examine the components of the rock cycle as well as how rocks can change over time due to weathering, erosion, pressure and heat. In particular, learners will model igneous, sedimentary, and metamorphic rocks. [Activity is publicly available through a web crawler capture on]
