Then came the labs.... get ready....
To engage the students I supplied each table with a set of rocks that I asked them to classify based on any physical property. They had to journal how they classified the rocks and draw a picture. My rock set had numbers on each rock which helped soooo much this week. Then we took a "Rock Tour" around the classroom looking at how each group classified their rocks and the students talked about whether they agreed with the placement or not.
Created rocks?!?!?! WHAT??
Yes... out of crayons... and it was messy.... but my psycho anal organized behavior did detour some of the mess.
First we made a fortune teller with 4 flaps labeled as sediment, sedimentary rock, metamorphic rock, and igneous rock.
Now it was time to make some rocks. It started with me buying 5 boxes of crayons (I bought the cheap stuff...this summer I am going to stock up when the back to school sale starts), 20 pencil sharpeners (0.47 each), and going to Lowe's (love them) and having them cut a huge board into 10 eight inch x eight inch squares. I know its a little expensive, but the learning experience is totally worth it.
2. Students then used their fingers to make the shavings into fine crumbs. This is important!!!
3. Place a small sample under the sediment flap of the foldable and place a piece of tape on top.
students draw a 10 cm x 10 cm square on the wax paper with a permanent marker. They then placed
all their crayon crumbs on the wax paper square.

5. Place the 2nd sheet of wax paper on top of the crumbs (wax paper crayon sandwich) and place it
between 2 of the square boards.
having them press on it for a few minutes. Do not hammer it unless you want a headache, or press with
their hands (I did this with my morning group and it did not turn out very well).
student take a small sample from their crayon sedimentary rock and tape it in their journal. They also
wrote that pressure formed the rock on the top flap.

12. Using a wooden clothespin, attach it to the side of the bowl. This is the handle.
13. Carefully using a hot plate, have the students melt the crayon sandwich (metamorphic rock)- be careful that someone is holding the handle of the bowl the entire time.
14. Using one of your boards as a trivet, place the bowl on it to cool down. Have students observe what happens and journal about it.
15. When it completely cools, have the students take a small sample and tape it into their journal.
