SIMPLE MACHINES
You are going to learn about three simple machines:
INCLINED PLANES, PULLEYS AND LEVERS are used to move heavy things.
AN INCLINED PLANE ( A RAMP) is a tilted surface which goes from a low point to a high point. It is used to move a heavy object. the smaller the incline, the easier it is to move the heavy object up and down.
A PULLEY is used to lift and lower heavy things. It is made up of a wheel and a rope or a cable.
The wheel has a groove in it and the rope goes around the wheel. HOW IT WORKS: When you pull down on one end of the rope the other end goes up.
SIMPLE MACHINES
A LEVER is made up of a rigid bar and a fulcrum. How it works: When we push down on one end of the rigid bar, the other end goes up. 3 different levers:

ARCHIMEDES
He lived in Syracuse more thatn 2000 years ago.
He invented among others: The Archimedes' screw and the Archimedes' Claw.
ARCHIMEDES' SCREW is used to transfer water from deep areas to higher areas. It is made up of a screw inside of a hollow pipe. how it works: The screw is turned around by hand using a crank.
ARCHIMEDES' CLAW is a weapon made to defend the city of Syracuse from Roman invaders. The CLAW had a hook that could lift an attacking ship. This would cause that the ship to sink.
Water is taken in at the bottom and travels up the screw as it rotates.
