100
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

Fill in the blanks. When you blow between two pop cans, the pop cans will move together. This happens because the fast moving air between the cans has ________ pressure, and the slow moving air surrounding the cans has ______ pressure. 

The fast moving air has low pressure, and the slow moving air surrounding the cans is high pressure.

100
This downward force on an aircraft is caused by gravity.
What is weight?
100
An invisible mixture of gases which make up the earths atmosphere.
What is air?
100
What is the part of the plane where the passengers sit

What is the fuselage

200

The property of air demonstrated by a ruler being partly covered by paper hanging off on the edge of a table. When the ruler is struck, it will snap in half instead of flipping up. 

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 gas that human blow out and makes up 0.04% of the air in our atmosphere.
What is carbon dioxide?
200

Is the elevator is located on the vertical or horizontal stabilizer?

What is the horizontal stabilizer?

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
A chemical reaction that takes place when a substance combines with oxygen.
What is oxidation?
300

What part of the plane controls the yaw? Hint:when the airplane turns side to side

What is the rudder?

400

The "diving paper" experiment demonstrated this property of air. The paper 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
The gases that occur in very small amounts in the atmosphere.
What are trace gases?
400

To have the plane roll to the left, what does the left and right aileron need to do?  (up or down)

The left aileron needs to be up and the right aileron needs to be down

500

The property used to explain why the balloon moved forward in the opposite direction of the air being released. 

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/gliding/stable?

500
The three gases that make up most of the atmosphere.
What is nitrogen, oxygen and argon?
500

What kind of shape helps air move around it to acheive lift?

Airfoil
