Summary:This activity allows students to experience what rocks and minerals go through during the rock cycle. The activity explains how to manipulate chocolate using heated water and a knife into different states representing metamorphic, igneous, and sedimentary rocks. Chocolate can be ground into small particles (weathered), heated, cooled, and compressed — just like rocks. Unlike rocks, chocolate can undergo these processes safely and at reasonable temperatures. Use your chocolate to create “sedimentary,” “metamorphic,” and “igneous” chocolate. And at the end of it all, make a tasty treat!
