1. Simple Machines
By Vanessa, Hanna and Malik

2. This is an example of an inclined plane. A real world example is a wheelchair going up a
ramp. This helps people who can’t walk up stairs. It allows you to push instead of carry
because the ramp is connected to the top of the stairs so all you have to do is ride up the
ramp. If you carry you are using a lot of energy.

3. This is an example of a lever. A real world example is a hammer. The hammer is putting a
nail in a board. This makes it easier to hang things in your house. As apposed to hanging
with tape or string, the thing you’re hanging will stay up longer.

4. This is an example of a pulley. A real world example is the American Flag’s rope. The guy
pulls the rope and it makes the flag rise in the air. If you didn’t have the rope, then you
will have to climb or use a ladder.

5. This is an example of a screw. The real world example is a light bulb. At the bottom of a
light bulb, is a screw. It helps the light bulb stay in it’s place. The light bulb would just
fall off.

6. This is an example of a wedge. The real world example is a door stopper. The wedge
helps stop the door from moving. You wouldn’t have to keep holding the door to go
through.

7. This is an example of a wheel and axle. A real world example is a bike. The wheel in the
front of the bike is a example of this simple machine. It helps the bike move.
