ROCKS: The Original Recyclers!
Rocks Have Options...
• Weathering: The wearing away or breaking down of rocks by…
1.2.3.4.5.
Rockin’ Terms:
• Erosion: The movement of sediments produced after weathering, usually by...
1.2.3.
Rockin’ Terms:
• Deposition: When sediments are dropped off in a new location after erosion.
Rockin’ Terms:
Step 1: Use the tools available at your station (pencil sharpener, cheese grater, penny) to shred your crayon-rock into a pile of shavings.

Let’s Recycle Some “ROCKS”!
Step 2: One at a time, each person should bring their shavings to the bigger piece of tinfoil.

Step 3: Take turns laying your shavings down, one color one top of the other.

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 30-60 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...
