In class today, we were challenged with the question of how certain independent variables; such as weight width or length, would affect the distance achieved by a paper airplane.
Our group had decided to make one airplane model based off of a record holding design for a paper airplane according to distance and aerodynamics.
We then used two paper clips as our dependant variables, changing their location to observe the shift in weight and balance. First we placed the paper clips on the tip of the airplane, then at the back, and finally we placed one on each wing. Although the location of the weight shifted, the independent variables remained the same; such as the weight, length, and width of the plane as well as the thrower as to keep the testing as precise as possible.
Although our hypothesis was that the plane with the paper clips attached to the tip would travel the furthest due to the gravitational pull and minimized drag, we found this hypothesis to be rejected. The data shown proves that in fact, the plane with the paper clips attached to the back travelled the furthest average distance of all three. We believe the reasoning behind this is due to the weight of the plane design. The design in itself is very front heavy, the various folds near the nose of the plane weighed down the plane even before adding extra weight. Whereas, when adding weight to the rear of the plane, the load seemed to balance and therefore carry itself further while remaining level.
Below, a visual of our paper plane design:
After completing this assignment, I learned the importance of even weight distribution among designs especially in aircrafts because when compared to real life this mistake could cause catastrophic damage.
In the future, I would take a few more steps to assure that I can improve upon my mistakes and revise my strategies. If I were to do this again, I would start by using a different or various different models of planes and compare how each model is able to carry the weight and why each one was successful.
