This hands-on experiment introduces students to the processes that form each of the three rock types: sedimentary, metamorphic, and igneous. Kids can see how any rock type can become any other rock type. A nice introduction or culminating activity for studying the rock cycle.
Use this to learn and reinforce answers to questions such as:
❑ What are the three types of rocks?
❑ How can one rock turn into a different type of rock?
❑ What are the processes involved in forming each type of rock?
Concepts Addressed
♦ There are three types of rocks (Sedimentary, Metamorphic, and Igneous
♦ Any rock type can become any other rock type through a series of processes
♦ Igneous rocks form from crystallized lava or magma
♦ Sedimentary rocks are formed from sediment that is cemented and compacted
♦ Metamorphic rocks are form when other rocks are under high temp and or pressure
♦ Minerals form from magma and lava
