Studying Moving Rocks
How do rocks move down a ramp? Find a board or piece of strong cardboard, and you can make a ramp or slide to see what happens when rocks are placed on that ramp. They may roll, slide on, or not move down the ramp. Gravity is the force that causes everything to move down on earth. When something does not move easily, friction is the cause. That usually happens with rough rocks.
