What are the 4 foces of flight?
Lift, Thrust, Drag & Mass
100
What are the 2 parts of a plane that are used for takeoff and landing?
Landing gear and flaps.
100
Why does an airplane have a streamlined design, similar to a birds?
To go faster, reduce drag and have less air resistance.
100
Why does a space shuttle have wings if there is no air in space?
To stabilize the craft during landing on Earth.
100
How does a hot air balloon control its side to side movement?
By moving up or down and catching moving air currents.
200
There is no ________ or _______ in space.
Oxygen or gravity.
200
Which plane part makes the plane rise?
Elevators
200
Explain how air and water have similar properties.
Both are able to flow over, under and around other objects. They can take the shape of the object in which they are contained.

Why would a person add air to a tire in winter, but take air out of the tire in summer? (Hint: Think about the experiment with the flask and balloon placed in hot and cold water.)
In the winter air cools and contracts taking up less space. The pressure inside the tire will be lower. In the summer, as air heats up it expands and take up more space. The pressure inside the tire increases.

How does a helicopter create lift?
Rotors act like wings. Blades are airfoil shaped and rotate quickly to generate lift. Low pressure above the blades and high pressure below.
300
How do you prevent a parachute from wobbling?
Put a small hole in the center to allow air to escape slowly.
300
How can you make a fire burn longer?
Make sure it has access to a lot of oxygen.
300
Write down the statement in which you can OBSERVE. 1. The effort a bird must give to achieve lift. 2. The size of a birds bones. 3. Whe wing shape of a bird or insect.
The wing shape of a bird or insect.
300
What are the 3 basic movements of an airplane?
Pitch, roll and yaw
300
What are 2 parts of a helicopter?
Rotor blades, rotor head, landing gear and tail rotor.
400
Draw an airplane, and label the 4 forces of flight.

400
Name 2 special adaptations that make it possible for a bird to fly (don't say they have wings)
1. Strong chest muscles 2. Specialized feathers 3. Hollow, lightweight bones 4. Airfoil shaped wings 5. Streamlined body
400
What do wings do?
Create lift
400
Name 2 parts of a parachute.
Canopy, load, shroud lines and air holes.
400
Draw and LABEL and airfoil shape. Label high pressure, low pressure, slow moving air, fast moving air and lift.

What is the job of the fuselage?
To carry passengers and cargo, as well as hold things together.
500
List 3 of the 5 theories/properties of air.
1. Air takes up Space. 2. Air exerts pressure. 3. Air can be compressed. 4. Air is fluid. 5. Bernoulli's principle.
500
How would you decrease the speed of a shuttle in space?
Put the engines in reverse.
500
How can you prove that air exists?
Flags moving on a windy day, blow on your hand etc....
