What you discover if you were to blow up one balloon and tie it on one side of a meter stick, while the other side has an uninflated balloon.
What is air has weight?
100
When you pump air into a bicycle tire.
What is air compressing?
100
This downward force on an aircraft is caused by gravity.
What is 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

These are shaped to make air move faster over the top of them. They are the main part of the airplane that help to create lift.

What are wings?

200
The property of air demonstrated by the cup of water being flipped upside down with a piece of cardboard on the top and the water doesn't spill out when the person's hand is removed.
What is air exerts pressure?
200
What happenes when air flows faster on the upper surface (less pressure) than the lower surface of an aerofoil (more pressure).
What is lift?
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

This provides the thrust to overcome drag and push the airplane forward through the air. 

What is the engine?

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 manufacturers shape an object such as a vehicle so it will move faster through the air.
What is streamlining?
300
The force that moves a plane forward through the air. This may be created by a propeller or jet engine.
What is thrust?
300
Both insects and birds have adaptations for flight. Name a similarity between the two.
Answers will vary.

This is a primary control surface used to steer an aircraft that moves through air. It operates by redirecting the air past the fuselage. It is a directional control surface along with the elevator and aileron. It is usually attached to the vertical stabilizer.

What is a rudder?

400
The "tissue in a cup" experiment demonstrated this property of air. The tissue did not get wet because...
What is air takes up space?
400
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?
400
The air resistance that tends to slow the forward movement of an airplane.
What is drag?
400
Name two special adaptations that insects have for flight.
Answers will vary.

This is the main body of an aircraft. It is an aircraft’s main body section that holds crew and passengers or cargo. 

What is the Fuselage?

500
The property used to explain the egg sucking bottle demonstration.
What is air can be compressed?
500
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.

This hinged flight control surface usually forms part of the trailing edge of each wing of a fixed-wing aircraft.  It is used in pairs to control the aircraft in movement which results in a change in flight path due to the tilting of the lift vector.

What is an aileron?
