There are different types of simple machine: the wheel and axle, pulley, inclined plane, screw, wedge and lever.
Inventions using simple machines help us in our everyday lives.

Machines all involve engines and need a power source.

Explicit teaching and explanation that simple machines do not often have moving parts and do not need a power source.

Mechanism - A mechanism is something which performs a task.
