Step 1: Use the tools available at your station (pencil sharpener, cheese grater, penny) to shred your crayon-rock into a pile of shavings. *Think back to the rock cycle terms...What process of the rock cycle are we doing? A.Erosion B.Weathering C.Depositing Let’s Recycle Some “ROCKS”!
Step 2: One at a time, each person should bring their shavings to the bigger piece of tinfoil. *Think back to the rock cycle terms...What process of the rock cycle are we doing? A.Erosion B.Weathering C.Depositing
Step 3: Take turns laying your shavings down, one color one top of the other. *Think back to the rock cycle terms...What process of the rock cycle are we doing? A.Erosion B.Weathering C.Depositing
Step 4: Carefully fold the piece of tinfoil in a square so the layers you created are all covered. Step 5: Take turns applying pressure. You can put the tinfoil between blocks and stand on them if you want. Try not to jump. That could rip the foil. Under Pressure...
Step 6: Carefully unfold the tinfoil and observe the new rock. Work as a team to identify the new rock. Step 7: Write in the name of the new rock on your rock cycle sheet. We have created a new kind of Rock!
Step 8: Work as a team to predict what will happen when your rock is heated and more pressure is applied. Step 9: Refold your tinfoil packet and bring it to a heating station. Heat for seconds. NEXT apply more pressure by putting it under the block and standing on it. Step 10: Carefully unwrap your rock and identify the new rock. Write in the name of the new rock on your rock cycle sheet Let’s Add a Little Heat and More Pressure...
Step 11: Get a “magma chamber” from the front. Place your rock in the chamber and bring it to a heating station. Once the rock is completely melted, carefully pour the magma into the water container. Step 12: Write in the name of the new rock on your rock cycle sheet. Melting it and Cooling it...
