Simple Machines

With Science at the moment we are looking at Simple Machines.  A simple machine makes work easier.  There are 6 different simple machines.

• Screw
• Inclined Plane
• Lever
• Wheel and Axle
• Pulley
• Wedge

Inclined Plane

An inclined plane is a flat surface which is tilted at an angle with one end higher than the other.  It either goes up (a ramp) or down (a slide).  It helps to move things either up or down.

We did an experiment with three different length inclined planes and found that the longer and less steep the inclined plane the less force (pushing or pulling) is needed.
