Lab 2: Paper Airplane Lab

Hypothesys: Because of my horrible paper airplane building skills, I believe my plane will spin out and crash at around 200cm, while the others will go about 400cm.
Independent Variable: Distance
Dependent Variable: Plane
Control Variable: Anything else (floor, for example)
Procedure:
1.) Build the paper airplane
2.) Gently throw outward
3.) Measure the distance in cm using a meter stick
4.) Write down the distance in a table
5.) Repeat 1-4 2 more times
6.) Calculate Average
Materials:
Paper Airplane
Meter Stick
Lab Notebook
Conclusion:
My plane actually flew more than 2 times as far as I had predicted. I thought it would fly aroud 200cm, but it flew an average of 434.66666...cm, and because plane 1 flew an average of 290cm and plane 3 flew an average of 209, my plane actually flew the farthest. Some errors that may have happened is that I may have measured incorrectly, had a fan on, or typed in the wrong numbers into my calculator. Next time, I will be sure that the fan is off.
