Exercise

Begin with a 20 minutes discussion on the rock cycle using the following URL as a visual. Walk the students through the rock cycle, highlighting the different stages which form the different types of rocks. The second 20 minutes have the kids do "observing effects of Pressure on Minerals" lab. Have students make golf ball size "rocks" out of modeling clay with beads distributed on the outside. Sandwich the model rock between 2 pieces of waxed paper and use their weight to apply pressure to model rock. Remove the waxed paper and observe the "metamorphosed" rock. The students can draw before and after pictures of their rock drawing arrows of where pressure was applied. Have them cute their rock in half and draw a crosscut picture.
