4 Inclined PlaneAn inclined plane is like a flat board that is higher on one end.A person on a wheelchair would use an inclined plane.I use one on the playground – the slide, of course!
5 Wedge A wedge pushes things away from each other. A wedge is 2 inclined planesput together like a V.Wedges split things.I use wedges every day –forks and knives, of course!
6 Screw A screw winds and winds around itself. Screws hold things together and can make them go up and down.I used screws - to build my birdhouse, of course!
7 Wheel and axle A wheel and axle is a pole and a circle. The pole lets the circle turn around it.You can use a wheel and axle to move things.I use a wheel and axle every day – my skateboard, of course!
8 PulleyThe pulley is like a wheel and axle with a rope instead of a pole.If you put a heavy thing on the rope and wind the other end around the wheel, you can pull the heavy thing.We use a pulley at school every day – to raise our school flag, of course!
9 Lever A lever is a board on top of something else. You can balance things or move them.Cave men used levers to move rocks.I use a lever every day – to open my can of soda, of course!
