Simple Machines make our work easy!

4. What are Simple Machines?"
"
Simple machines are tools that make our lives
easier. These tools enable us to use less
energy and less force to do work."

5. There are six types of Simple
Machines?

Lever
Incline Plane
Wedge
Screw
Pulley
Wheel & Axle

6. Lever
There are two parts that make up
the lever. The bar, which is called
the arm and the fulcrum or pivot
point. The lever helps us lift things
easily.

Here are some examples of a Lever that I found in the classroom. Can you think
of some other examples of a lever in your home or in the school building?

8. Inclined Plane"
"
"
The Incline Plane is made up of a straight plane
that is tilted up. Heavy objects can be moved
from lower levels to higher levels."

11. Examples of the Wedge
BOOK ENDS
DOOR STOP
Here are some classroom and office tools that are wedges. Can you think
of any other examples of a wedge?

12. Screw"
"
"
"
The Screw is made up of an incline plane
wrapped around a pole. It holds objects
together or drills holes."

13. Examples of the Screw
DOOR HINGE
SWING HINGES
These screws help hold these objects together. Can you think what else screws
hold together?

14. Pulley
A Pulley is a made up from a wheel that is
wrapped with a cord or rope. A pulley
changes the direction of force and makes it
easy to hoist or lift objects.

PULLEYS CAN YOU THINK OF?

16. Wheel & Axle
A Wheel & Axle is a simple machine
made of a wheel that turns on a cylinder
or post, to help objects move quickly.
