2 Simple Machines

3 1.Simple machines help us do work. 2.Machines make work easy. 3.There are 6 kinds of simple machines.

4 The 6 kinds of simple machines are: 1.Inclined plane 2.Wedge 3.Screw 4.Wheel and axle 5.Pulley 6.Lever

5 Inclined Plane 1.An inclined plane is like a flat board that is higher on one end. 2.A person on a wheelchair would use an inclined plane. 3.I use one on the playground – the slide, of course!

6 Wedge A wedge pushes things away from each other. A wedge is 2 inclined planes put together like a V. Wedges split things. I use wedges every day – forks and knives, of course!

7 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!

8 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!

9 Pulley The 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!

10 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!

11 They make my life easy and fun! Simple machines are GREAT!
