One possible school project involving a simple machine is an experiment with an inclined plane. Create an inclined plane (a ramp) with books and, with the use of a rubber band, show that it takes less force to move an object, like a bag of pebbles, up the inclined plane than it does to move it without one. An inclined plane is a flat surface, one end of which is higher than the other.Full Answer >
