Number Of Wings Hypothesis: If there are three wings on our rocket, then it will go the farthest because it might be too heavy if we add more than three wings. Data: Number of Wings Trial 1

Controlled Variables: Same person pulling the string Same size wings Same tilt of the wings Same bottle Control Rocket: Angle: 30 Degrees Nose: 100 ml water Body: 400 ml water Wings: 10x5 Right triangles Procedure: Tape the bottoms of a 20 oz and a 2 liter bottle together with duct tape. Then cut out four 10x5 cm wings. Wrap the wings with one layer of duct tape each. Tape two wings onto the 2 liter bottle evenly spaced. Launch the rocket at least two times, if the two results are reasonably close then stop at two trials. If they aren't reasonably close, then record a third trial. Next you have to test the flight distance of three wings. Tape three wings to the bottle, evenly spaced. Do the same thing as before, running at least two trials. Next test four wings. Tape for wings to the body of the rocket, evenly spaced. Record the distance that each rocket flew. Conclusion: Our hypothesis was incorrect. We predicted that three wings would make the rocket travel the farthest, but the results showed that it covered the most distance when there were four wings attatched to it. If we had more time we would test the distance the rocket would go if it had more than four wings. If we had the chance to do it over again we would test the shape or angle of the wings also.
