1. ROCK around the Clock

2. Question/Problem What are the forces and processes of the rock cycle?

3. Hypothesis No hypothesis for this “lab”…it is more of a demonstration

4. Materials Pencil and Paper Crayons Baby food jars Pencil sharpener Hot plate Aluminum foil Big paper

5. Procedure 1.Get materials 2.Cover your table with paper 3.Trade in 4 of your crayons with another group, so that you have 8 total crayons, 2 of each color 4.Shave the crayons with your pencil sharpener, keeping the colors separated in its own pile

6. Procedure 5.Place 1 pile of the crayon shavings on the aluminum foil. Spread the shavings around so they form a “square” roughly 1 cm thick 6.Layer the rest of the crayon shavings on top of this square, being careful to minimize the mixing of the colors. You will have 4 color layers when this step is finished 7.Fold the foil around the crayon pile tightly. 8.Press down on the pile with the science book.

7. Procedure 9.Unfold the foil, and make and record observations of your crayon “sandwich” 10.Break the sandwich in half, and make and record more observations 11.Rewrap the foil with the pieces on top of each other, and place between the book again 12.Press down AS HARD AS YOU CAN, rock back and forth, have a teammate help squish the foil

8. Procedure 13.Repeat steps 9 and 10 14.Place the crayon chunk into your baby food jar, and place on the hot plate 15.Observe what is happening, and record observations 16.When the crayon has completely melted, remove from the heat using the oven mitt, and allow to cool 17.Make and record observations

9. Data-for this lab, answer the following questions 1.These are questions to answer beyond the observations that you make during the experiment. 2.What step of the rock cycle is represented by shaving the crayons? 3.What step is represented by pressing on the shavings with the book? 4.What step is represented on the hot plate?

10. Conclusion What did you learn about the rock cycle? If you had to explain the rock cycle to a 2nd grader, tell me specifically, step by step, how you would explain this to a 2nd grader.
