Simple machines are mechanical devices that are used to make forceful tasks easier. There are six simple machines: the inclined plane, the lever, the wheel & axle, the pulley, the screw, and the wedge. Throughout the activities in this unit, learners will explore how they can use each of these simple machines to move different materials in a way that helps to accomplish a task. They will race cars, catapult pom poms, transport blocks, lift building materials, transfer small and delicate items, and use tools to cut through dough.
