Properties of Air
Does air have mass and take up space?
Yes? (Air is matter, and all matter has mass and volume)
Name the upward force that opposes gravity.
Lift
Does fast-moving air create high or low pressure?
Low Pressure
Which wing surfaces are used to "roll" the plane?
Ailerons
Name one way air travel impacts the environment.
Carbon Emissions
What happens to air particles when they are heated?
They expand (or move further apart)?
This force is a "pull" toward the center of the Earth.
Weight
What is the specific curved shape of a wing called?
Airfoil
Does the "elevator" on the tail control pitch or yaw?
Pitch
Give an example of a "propulsion" system used by a bird.
Flapping of a bird's wings
This term describes the force exerted by air particles hitting a surface.
Air Pressure
Name the forward force produced by an engine or propeller.
Thrust
Why is the top of an airplane wing curved?
to make the air move faster? (Creating lower pressure on top than on the bottom).
This part of the tail moves side-to-side to control "yaw."
Rudder
What is one benefit aviation provides to Canadian society?
Connecting remote communities (or fast transport of goods/emergency meds)
Why does a balloon expand when you blow into it?
Increased air pressure? (The air particles inside are hitting the walls harder than the air outside)
This force is a type of air resistance that slows a plane down.
Drag
How do "flaps" help a pilot during takeoff or landing?
by increasing lift at slow speeds? (They increase the surface area and curve of the wing).
Describe the movement of a plane when it "pitches."
The nose moving up or down
Identify a career or skilled trade in the aviation industry.
Aircraft Maintenance Engineer (or Pilot/Air Traffic Controller)
Science considers air a "fluid." Name one other common substance that is also a fluid.
Water (or any liquid)
If a plane is at constant speed and altitude, what is the state of the four forces?
Balanced? (Lift = Weight and Thrust = Drag)
If you blow air over the top of a paper and it rises, what principle are you showing?
Bernoulli’s Principle
To turn left, how must the ailerons move?
Left Aileron Up, Right Aileron Down
Name one way the industry is trying to reduce its carbon footprint.
Electric Engines (or using Biofuels/Lighter materials)
