When we blow into a balloon it fills up.
What is "air takes up space"?

It is hard to drive on a flat tire but easy to drive on a full tire.
What is "air exerts pressure"?
It buzz's and likes flowers.
What is a bee?
The force that pulls the airplane down.
What is weight?
Name of the shape of the airplane wing that creates lift.
What is airfoil?

What are thrust, drag, lift and weight?
The principle that the faster air flows, the less pressure it has.
