How does it work?

How does it work?
How does it go?
How does it move?
How can we know?

Electricity, the wind, motors and man;
All move machines
The best that they can.

Wind power moves our windmills and kites.
Electricity powers machines and lights.
Motors run our cars, boats and vans.
Bicycles are machines powered by man.

How does it work?
How does it go?
How does it move?
How can we know?
