The Rock Cycle - Part 2

After creating sedimentary rock by pressing the pieces of sediment together, we wrapped our sedimentary rocks in aluminum foil and applied heat and pressure with our hands.  The heat and pressure changed our sedimentary rocks into metamorphic rocks.

To continue the rock cycle, we applied even more heat (an electric griddle) to our metamorphic rocks to create magma.  Our rocks quickly melted and began to bubble!

Once the magma cooled, we were left with igneous rocks!
