When you pump air into a bicycle tire.
What is air compressing?
100

This downward force on an aircraft, bird, or insect in flight. 

What is gravity/weight?

100
It is shaped to allow fast moving air to move on top of it and slower moving air on the bottom.
What is an aerofoil shaped wing?
100
An invisible mixture of gases which make up the earths atmosphere.
What is air?
200

The property demonstrated by pouring water into a sealed container through a funnel. 

What is air takes up space?

200
When manufacturers shape an object such as a vehicle so it will move faster through the air.
What is streamlining?
200
The upward force that is created by the movement of air above and below a wing.
What is lift?
200
The purpose of a bird's strong chest muscles.
What is stronger muscles means that the bird can flap it's wings more often?
200
The gas that human blow out and makes up 0.04% of the air in our atmosphere.
What is carbon dioxide?
300
The property of air that is demonstrated when air is blown around a canand the flame of a candle on the other side goes out.
What is air is a fluid?
300
When air flows faster on the upper surface (less pressure) than the lower surface of an airfoil (more pressure), creating lift.
What is Bernoulli's Principle?
300

The force that moves a plane/bird/insect forward through the air.

When a container is sealed that has warm air in it. 

What is it will implode as the air cools and contracts?

The property of air demonstrated by the "Cartesian Diver" - the eye dropper in the pop bottle that you can raise and lower by squeezing. 

What is air can be compressed?

500

To the forces of flight when an aircraft descends and slows down.

What is drag and weight are increasing, lift and thrust are decreasing?

500
When all four forces are equal, this will happen.
What is hovering?
500
Name one difference between the way an airplane and a bird flies.
Answers will vary.
