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.
