Wheels and Axles Teacher Info

The wheel and axle is a simple machine with a wheel and a rod going through the center of it. When students complete the activities on wheels/axles they should be able to explain how wheels/axles help to pull. Lift or move heavy loads with less effort. The larger the diameter of the wheel, the less effort that is required. Students can use yarn to determine how big the diameter or the circumference is. (Wheels have axles, pulleys have ropes or chains instead yet operate similarly.)

*It is important for students to have the opportunity to see and use wheels/axles often found in toy building materials similar to LEGO, K-nex, miniature cars etc.

Examples of Wheels/Axles: Rolling pins, roller skates, push carts, vehicles, wagons, screwdrivers, bike wheels, skateboards, door knob, pencil sharpener.
