Analysis With 0 pc’s, the mean flight time was ____ sec. After adding 1 pc, the time _______ to ___ sec. With 2 pc’s the flight time continued to _____ to ____ sec., and the time with 3 pc’s was ___ sec. After 4 pc’s the time continued to ______ to ___ sec., and the final flight with 5 pc’s had a mean flight time of ____ sec. As weight increased, the mean flight time ____.

Conclusion Adding weight ______ flight time. The hypothesis was __________ (accepted, rejected).

Hmmm… Anything missing? 1.Fly the helicopter. 2.Time it. 3.Do it again with more paperclips. 4.The end.

Constant Variables a.k.a. Constants Inside the “C”… Something that must be kept the same for both groups or it will not be a fair test. Inside the “C”… Something that must be kept the same for both groups or it will not be a fair test.

Independent Variable Inside the “ I ”… The one thing you choose to do differently; sometimes called the “cause”. Inside the “ I ”… The one thing you choose to do differently; sometimes called the “cause”.
