Physical weathering refers to the breakdown of rocks without a change in their chemical composition. When rocks are subjected to external forces, such as shaking, they can experience mechanical stress and break into smaller pieces. By placing cookies in a box and shaking it, the student can simulate the physical processes that cause rocks to weather and break apart.
