Chocolate Chip Rock Cycle
Students placed different colored sediments (chocolate chips) into a plastic bag and crushed them into smaller sediments. They used pressure (books) to compact the sediments into sedimentary rocks. Their sedimentary rocks were then changed into metamorphic using heat and pressure (warms hands). Students then carefully placed their bags into warm water to melt the chocolate chips into lava. After cooling we had igneous rocks!
