What is a simple machine? A simple machine is a machine with few or no moving parts such as a gear, lever, pulley, screw, inclined plane, wedge, or a wheel and axle. One of the favorite jobs on our class job board is the “Flag Raiser” because our classroom flag is on a pulley which is raised and lowered each school day!
Thank you also to the HPTA funded program "Techsploration" : a fantastic, upfront, zany exhibition of how simple machines trade distance for effort to make work easier. Perfect for third graders!
