Place a paper boat in a ditch, and then use water from a hose to make it sail away.
The activity that best models the physical weathering of rock is: "Place several cookies in a box, and then shake the box." This activity simulates the mechanical breakdown of materials, similar to how physical weathering such as abrasion or impact can break rocks into smaller pieces.
