Overview
This is the last in a series of posts looking at Simple Machines (Lever, Wedge, Inclined Plane, Pulley, Wheel and Axle, Screw). Becoming more aware of the Levers, and other Simple Machines, that exist in your early learning setting will make you more confident supporting STEM (Science, Technology, Engineering, and Math) play and answering children’s questions about how many everyday items work.
What’s A Wheel And Axle?
A wheel and axle involves two circular elements joined at their centers–a larger disk (the wheel) and a smaller cylinder (the axle). On their own, a wheel is just a wheel and an axle is just an axle, but combined they become a simple machine.
Wheel And Axle Examples
How A Wheel And Axle Work
A wheel and axle works differently depending on where force is applied. In tools like screwdrivers and doorknobs, force is applied to the wheel (the screwdriver’s handle or the doorknob’s nob) which turns the axle. Alternatively, force can be applied to the axle which turns the wheel–like in cars and Ferris wheels.
Conclusion
I’d love to see and hear about Wheel And Axle play in your early learning setting–share your thoughts and photos in the comments.
