We brought the rock portion of our unit to a close with a look at metamorphic rocks. The kids had a tough time deciding which rock sample was marble and which was quartzite.
We also did the melted-crayon version to show how metamorphic rocks form under heat and pressure. Okay, so really we just made rainbow crayons, but the kids *said* they understood how the rocks can change because of the heat!
One book that talks specifically about metamorphic rocks is Baking and Crushing. It is recommended for grades 1-3. That goes right along with our baked metamorphic rock activities here with crayons and here with cake and core sampling that we did a while back!
