We looked at simple machines in our school. They are: Inclined plane, wedge, lever, pulley, wheel and axel, and screw.
A inclined plane is used to move things from a high to low surface.
A wedge is used to separate objects.
A lever is used to lift up heavy objects.
A pulley is used to lift up our flag.
Wheel and axel helps a car tire move.
A screw is used to hold objects together.
