The document discusses different types of simple machines, including inclined planes, levers, pulleys, wheels and axles. It provides examples and diagrams of each machine, explaining how they make work easier by reducing the amount of force needed. Key parts of each machine are identified. Activities include labeling diagrams, identifying simple machines in pictures, and completing sentences about how they function. The document concludes with links to educational websites about simple machines.

3. Kinds of Simple Machines A simple machine is a device that makes work easier. Some examples of simple machines are: Levers Wheel and Axle Pulleys Inclined Plane

4. Inclined Plane An inclined plane is a slanted surface that makes it easier to move a heavy object. You need less force to push an object up an inclined plane, but you move it a longer distance . Photo courtesy of Scholastic.com

5. Parts of an Inclined Plane Can you label the parts of the inclined plane below? load force inclined plane

6. Examples of Inclined Planes

7. Lever A lever is a long stiff bar that rests on a point called a fulcrum. The fulcrum does not move. Force is put on one end of the lever. The other end lifts a load . Photo courtesy of Scholastic.com

12. Pulleys A pulley is a wheel with a groove that holds a rope or a chain. A person holds one end of the rope. This force lifts the load on the other end. Photo courtesy of Scholastic.com
