1. Simple Machines By Anna Maslowski and Sylwia Jablonska

2. What is a Simple Machine? A simple machine is what you can use to make work easier. There are 6 types of simple machines: lever, inclined plane, wheel and axle, pulley, screw and wedge.

3. LEVERS This is a first class lever.

4. Levers A lever is a bar that is free to turn around a fixed point. There are 3 types of levers: a first class lever, a second class lever and a third class lever. A lever is a bar that is free to turn around a fixed point. There are 3 types of levers: a first class lever, a second class lever and a third class lever. For example a 1 st class lever is a crowbar, a 2 nd class lever is a wheelbarrow and a 3 rd class lever is a broom. For example a 1 st class lever is a crowbar, a 2 nd class lever is a wheelbarrow and a 3 rd class lever is a broom.

5. INCLINED PLANE Yay…GREEN!!!!!!!!!!

6. Inclined Plane An inclined plane is a slanted surface or ramp. It makes work easier by changing the angle at which you have to exert force to lift resistance. A screw in an inclined plane wrapped around a cylinder. An inclined plane is a slanted surface or ramp. It makes work easier by changing the angle at which you have to exert force to lift resistance. A screw in an inclined plane wrapped around a cylinder. IMA (ideal mechanical advantage) = length/height IMA (ideal mechanical advantage) = length/height

7. SCREW A screw is like a wedge with an inclined plane wrapped around it. It goes in to things easily with its point and is easy to sink in because of the threads.

8. Wedges and Screws A wedge is a kind of inclined plane. A wedge is most often made of 2 inclined planes,( or screws) back-to-back. A wedge is a kind of inclined plane.

9. Pulley A pulley is a rope wrapped around a wheel. Pulleys can change direction of a force, size, or both. A pulley is a rope wrapped around a wheel. Pulleys can change direction of a force, size, or both. There are 3 types of pulleys: a fixed pulley, pulley system, and movable pulleys. There are 3 types of pulleys: a fixed pulley, pulley system, and movable pulleys.

10. WHEEL AND AXLE An example of a wheel and axle is a door knob.

11. Wheel and Axle A wheel and axle are 2 different sized wheels that turn together around the same point. An example of a pulley is a door handle. A wheel and axle are 2 different sized wheels that turn together around the same point. An example of a pulley is a door handle. A wheel and axle is like a lever that moves in a circle. A wheel and axle is like a lever that moves in a circle.
