The plane with wider wings will fly longer.
I used paper, a timer, and the gym.
The independent variable is the wing design. The dependent variable is the lift time. The control variable is the standard plane.
The constant variable: I will throw each plane with the same velocity. The only thing I changed was the wing design. I kept everything else the same like the fuselage and the nose, etc.
When I threw the plane, I had a timer time it while it was in the air.
The wings that were wider stayed in the air longer.
My hypothesis is right. The planes with wider wings stayed in the air longer. The glider was 1.6 seconds faster than model 2. The reason the glider stayed in the air longer was because the wings were like a parachute. They began to resist gravity because the air on top of the wing was going faster than the air on the bottom so that made an upward push on the plane's wings making it stay up longer.
People who build toy planes could use this study when they build planes because the kids like the planes that fly longer. So they could make lots of money off toy planes just by making the wings wider.
