## 1 - Introduction

### What causes the lift?

• Answer questions 1 to 6 on the A3 summary sheet (see related files below) using complete sentences. (This should take no longer than 5 minutes.)
• Video (Watch 25 minutes)

### Bernoulli's Principle

Blow between two pieces of paper which are held, suspended vertically and try to blow them apart.
Watch as air is blown between two ping pong balls.
Watch as air is blown through funnel with ping pong ball inside.
Explain why the ping pong ball stays in the air stream.
Watch as air is blown over a piece of wood shaped like an aircraft wing.
On the A3 summary sheet (see related files below), explain why the wood behaves as it does. You should include a diagram of the shape of the wing.

## 3 - Paper Plane

### Instructions and challenges

• 1 - Fold an A4 paper as shown in the instructions.
• 2 - Gently launch your plane as shown by your teacher.
• 3 - Follow the instructions to enable you to control the direction in which your plane flies.
• 4 - Make several smaller planes of the same design, calculate the mass of each plane (1 A4 sheet has a mass of ...g) and evaluate which is the best for remaining in the air the longest. You will have to test each under the same conditions.
• 5 - On the A8 summary sheets, write your findings.
Work through questions 1 to 18 writing your findings on the A8 summary sheet.
