3rd Grade Students Discover Simple Machines

Cactus Ranch 3rd grade students learned about six simple machines including the pulley, wheel and axle, screw, inclined plane, wedge, and lever. Each student created their own simple machine project and presented to their class a demonstration of how their simple machine worked. Harley from Ms. Jenkins class demonstrated her knowledge about levers by creating a Prezi presentation.
