A single rock could provide an example of how slowly most geological changes occur on Earth. If you picked up a rock and kept it for the rest of your life, you would probably notice that it changes little, if at all. Yet, rocks can and do change; it often just takes quite a long time. Many factors cause rocks to change, but what is important to understand is that change does occur. This activity allows students to explore the rock cycle with a physical model made from colored crayon shavings. They form the shavings into layers, compress them, and ultimately melt them, replicating pathways a rock can take in the rock cycle.
