A Little Background on Simple Machines
Only a few steam engines are still in operation. Canadian Pacific keeps this old steam engine running to celebrate history.
How difficult would our lives be if we did not have machines or devices
that move? Just think – there would be no airplanes, trains, boats, or
cars. Building things would take much longer because we would have no
power tools.
Thankfully, humans have been making machines and devices that move for hundreds of years, and it all started with the some of the simplest of machines: levers and wheels.

A wheelbarrow is an example of a device that moves that is built with
simple machines. The complete wheelbarrow is a lever that makes lifting
a heavy load easier. The wheel and axle at the front allow the
wheelbarrow to roll easily over the ground.
Sometimes simple machines let you move things faster. Sometimes simple machines let you be more forceful. The key to all simple machines is making our lives easier.
