How I will conduct the experiment?

My experiment will answer the question:
'How does size of paper used to make paper airplanes affect their flight.'
 
Following the research about the aerodynamics of paper airplanes/planes in general and brief plane launcher design, here is a rough summary of how I will conduct the experiment.

Equipment:

Independent Variables:

- model of airplane

- size of paper

Dependent Variables:

- length of flight

- nature of flight (not sure if I should do this one)

ie, pattern of flight of the plane, how quickly it descends.

Controlled Variables:

- type of paper used

- wind speed in surrounding environment (that will be 0km/h as I will conduct at home)

- length elastic band is pulled back (is there a name of that?)

- height of release

Method 1:

Using the three models of airplanes I had previously decided on, I will launch each model from the plane launcher.

I will vary the size of paper used, starting from an A4 size followed by paper of smaller sizes.

I will then measure the distance travelled by each airplane of each model. Record the results, repeat the experiment, and of course, analysise.

Method 2:

A method similar to the first, with the difference of recording the 'nature of the flight'.
ie, recording the actual flight of the airplane and perhaps graphing it.
