Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. Finally, students design their own use for an inclined plane.
