Definitions:
Lift: The air pressure is greater underneath the wing than above and the aircraft / bird files.
Drag: The force than effects the speed of an aircraft / bird. It can slow it down.
Thrust: The forward movement of an aircraft / bird.
Gravity / Weight: The downward force of an abject when it is above earth.
Aerofoil: The shape of the wing on aeroplanes and some birds.
Bernoulli Effect: When a wing is in the shape of an Aerofoil the pressure builds up underneath it and it lifts the aeroplane up.

Activity 1: Your challenge is to hold a rectangular piece of paper close to your mouth, blow across the top of it and get the paper to move down. Sounds simple enough but give it a go and see if you change your mind.
What is happening? There is more pressure on the top of it s it want it lift up. This is called the Bernoulli effect.
Activity 2: Try and make a piece of paper into a simple bridge and get the bridge to rise up by blowing under it.
What is happening? The pressure is pushing it up
