In the first lab, kids make models of three types of rock: sedimentary, metamorphic, and igneous. As they build each of the rocks, they’ll develop a clearer sense of what’s going on in the rock cycle and the processes involved in forming each of the three types of rocks. They’ll see the fragility and granular nature of sedimentary rocks and easily differentiate them from the harder and more uniform igneous version of the rock. In the second activity kids travel through the rock cycle, recording
