Simple Machines Make Work Easier
A simple machine helps you do work with less effort. There are six of them and they are hiding in almost every tool ever made!
The Lever ⚌
A lever is a bar that tilts on a pivot point called the fulcrum. A seesaw is a lever! Moving the fulcrum closer to the heavy side makes lifting much easier.

Seesaw = Lever!
When you sit on one side of a seesaw and your friend sits on the other, you are both using a lever!
The Ramp (Inclined Plane) 🌀
A ramp lets you slide things up gradually instead of lifting straight up. Wheelchair ramps and loading docks use this idea. Less effort — same result!
The Wheel ⚙
A wheel and axle lets things roll instead of drag. Rolling takes much less effort than dragging. Cars, bikes, shopping carts — all use wheels!
