FLIGHT

Aim: To learn about flight and aerodynamics. 

• In your groups of 3 you will make a paper plane and measure its distance and behaviour.
• In groups of 3 you will make a water rocket and record its distance and behaviour. 

Definition: 
The action or process 
of flying through the air

4 forces of flight:

1.   gravity
2.    thrust
3.   drag
4.    lift  

Paper Plane:

Material:

1. paper
2. ruler
3.paper clip 

Steps:

1. fold it in half. 
2.  fold the  corners in the middle.
3. fold it in half again.

Findings:

Plane Type	Distance	Behaviour
Normal	3.0	straight line
Ailerons	.7	cured back
Paper clip	3.2	straight line

Conclusion:
 In our group the one that went the furthest is the paper clip one because the paper clip one was weighting it down so it made it gelid  to 3.2 metiers. The wing were very big so it would of made it gelid further then all the other planes.  
The paper plane that was normal flew 3.0 metres in a straight line. 
The paper plane that was the Ailerons flew .7 in a cured back.
The paper plane the was the paper clip flew 3.2 straight line 





Water Rocket

Material:

1. bottle  
2.  cardboard 
3. paper 
4. nose con e
5. scissors  
6. glue 

Steps:

1.  cut the bottle in half 
2. cut out three or four fines 
3. glue the fins on the bottle  
4. glue on the nose con e 
5. 
6. 
7. 

Findings:

( Record the distance and the flight behaviour of your rocket.)

Fuel Amount	Test 1	Test 2	Test 3
⅓ water	not far	feather	really far
½ water	not far	feather	really far
¾ water	not far	feather	really far

Conclusion:
