6th grade
Fluid
A substance, as a liquid or gas, that is capable of flowing and that changes its shape when placed in a new container.
Pressure
The weight or force that is produced when something presses or pushes against something else.
Air
It is all around us, we need it to breathe, but we can't really see it, yet we can for surely feel it.
Density
The amount of mass in a specified space.
Buoyancy
The ability to float.
Lift
The upward force that is created by the movement of air above and below a wing. Air flows faster above the wing and slower below the wing creating a difference in pressure that keeps an airplane up.
Thrust
The force that moves a plane forward through the air. This force is created by a propeller or a jet engine.
Weight/Gravity
A force that acts on a plane or an object that pulls it back to earth.
Drag
The force that tends to slow down the forward movement of an object such as a plane.
Bernoulli's Principle
The air moving over an airfoil travels faster over the top creating a lower pressure than the air that is traveling slower on the bottom, The air on the bottom of the airfoil is traveling slower and creating a higher air pressure resulting in lift.
Aerodynamic
The science of moving through the air.
Aileron
The sections of a wing that can move up or down and control the roll of the airplane.
Airfoil
The shape of a wing that helps to create lift in either man-made things or natural things.
Rudder
The vertical stabilizer on an aircraft. It controls the yaw of the plane.
Elevator
The horizontal stabilizers, or the part of the airplane that controls pitch.
Yaw
The direction the airplane is flying when it banks to the left or banks to the right. The rudder, or vertical stabilizer, controls this.
Pitch
The direction of the nose of the airplane. It determines whether the airplane is climbing or diving. The elevators, or horizontal stabilizers, control this.
Roll
Ailerons control this.
Right - The left aileron must be up and the right aileron must be down.
Left - The right aileron must be up and the left aileron must be down.
Fuselage
The main body of an airplane.
Wing
The main item on a plane or the adaptation of birds and insects that allows them to fly.
Aircraft
A man-made machine that is able to fly by taking off from the earth and overcoming weight to create lift.
Spacecraft
A vehicle or machine designed to fly in outer space.
Rust
The formation of reddish-brown oxides on iron because of water. The iron breaks down.
What is the difference between spacecraft and aircraft?
Talk about:

What are the 6 principles of air
air exerts pressure
air is everywhere
air takes up space
air has weight
air can be condensed
air acts like a fluid
