Yesterday, students used a variety of chocolate chips to create an edible rock cycle. We put white, dark, and butterscotch chips in a plastic bag to begin our experiment. Students crushed the chips to represent sediment. Once they crushed the chips they applied pressure ( to create sedimentary rock) with their hands to cement them together. Next, they put their plastic bag in hot water which turned our chips into magma (metamorphic changes). We quickly put the bag into an ice bath which hardened the chips into lava (igneous rock). Students looked for crystals (butterscotch chips) to decide if they had an intrusive or extrusive rock. Then it was time to eat!
