Edible Rocks Lesson

Igneous- Igneous rock forms from hot, melted lava that cools and hardens into a rock. To simulate this, we melted chocolate chips and then put a "dollop" on wax paper. We smoothed it out under the wax paper and then put it in the freezer. When it came out, it was solidified into another shape!


 Metamorphic- Metamorphic rock forms when two or more types of rock merge together from pressure over time, as well as heat. To simulate this, each student received a piece of white bread and a piece of wheat bread. Using their fists to pound them, and rolling pins to merge them, students were able to combine the two "rocks" into one new flat "rock"!


 Sedimentary- Sedimentary rock forms when layers of "sediment" merge through time from pressure and heat. To simulate the layers, we first put down a layer of cookie dough in a pan. Then we added layers of chocolate chips, M&Ms, raisins, white chocolate chunks, and sprinkles!!! To represent the "heat" we baked it and out came a delicious new rock!
