1. Carefully grate different colored crayons to create “grains” of different sizes
2. Add a small amount of two different colored grains to the wax paper. Fold paper over and apply pressure with your hands. Observe.
3. Repeat Step 2 but use iron to apply both pressure and heat. Observe.
Questions to consider:
What effect does pressure have on the grains?
What effect does heat have on the grains?
How can you observe this in nature?
