In this 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.

☀ How do sedimentary rocks form?
☀ What types of rocks can show no grains?
☀ How do igneous rocks form?
Topics & Concepts Addressed:
✦ Sedimentary rocks are made of sediment that's compacted.
✦ Metamorphic rocks are made when rocks are heated and pressed.
✦ Igneous rocks are made when magma cools
