Properties of Air
This property explains why a balloon holds its shape when tied.
Air takes up space
The force that pushes an airplane upward.
Lift
When a car suddenly stops and passengers lean forward, this scientific idea explains it.
Newton’s First Law: Inertia
The movement where the nose moves up or down.
Pitch
Birds have hallow bones to *blank* which helps them *blank*
Birds have hallow bones to reduce their weight which helps them fly
A fully inflated basketball weighs more than a flat one because air has this.
Mass
The force that pulls the airplane downward toward Earth.
Gravity
When you jump off a boat and it moves backward, this explains it.
Newton’s Third Law: Equal & Opposite Reaction
The movement where the plane tilts one wing higher than the other.
Roll
A bird carrying a heavy stick may struggle to fly because this force becomes stronger.
Gravity (weight)
When you stick your hand out of a moving car window and it pushes backward, this property is being shown.
Air resists things moving through it
If drag becomes stronger than thrust, the airplane will do this.
The airplane will slow down
If you push something harder and it speeds up more, this idea explains it.
Newton’s Second Law: Acceleration
The movement where the nose turns left or right.
Yaw
A truck and bicycle move at the same speed. Which is harder to stop and why?
The truck, because it has more mass and more inertia.
Tires need more air in winter and less in summer because air does this when heated and cooled.
Air expands when heated and contracts when cooled
If thrust is stronger than drag, the airplane will do this.
The airplane will speed up
Bernoulli’s Principle explains that faster-moving air has this.
Faster-moving air has lower pressure
This would happen if a plane could not yaw or roll.
The plane would not be able to turn
Explain why a heavier airplane needs more thrust to take off.
More mass means more inertia, so more force is needed to accelerate.
When you suck on a straw and liquid moves up, this property of air is working.
Air exerts pressure
Name ALL four forces of flight.
Lift, gravity, thrust, and drag
Explain how Bernoulli’s Principle helps create lift on a wing.
Faster air over the top lowers pressure, slower air underneath has higher pressure, pushing the wing upward.
These parts of the plane control pitch, roll and yaw.
Elevator (pitch), Ailerons (roll) and Rudder (yaw)
A bird who lives in a dense forest would need *blank* type of wings. Explain why.
Short, rounded wings allow for quick takeoff, sharp turns, and better control in tight spaces. In a dense forest with lots of trees and branches, the bird needs to maneuver quickly and avoid obstacles, rather than glide long distances.
