This lab is a very simple and fun way to teach students about the rock cycle. Students are able to see how crayon shavings (you can have students obtain these with a plastic knife or you can use a crayon sharpener) can be pressed, heated and liquified to become the various stages (sedimentary, metamorphic, igneous) of the rock cycle. My students always enjoy making new types of wax and seeing the "rocks" that they make! Have fun!
Materials needed: crayons (at least one per student), VERY hot water, aluminum foil squares, beaker (large), plastic knives
The designed PDF can be enjoyed the way it is, but a straightforward editable word doc is included as well.
