The Crayon Rock Cycle
In this activity, crayons will be used to demonstrate the various steps of the rock cycle. Crayons have the ability to be ground into small particles (weathered), heated, cooled, and compressed just like rocks. However, unlike rocks, all these processes can be done safely and at reasonable temperatures. Using crayons, students will be able to create sedimentary, metamorphic, and igneous crayons (rocks).
