Question: How Does The Size Of The Wings Affect

Question: How does the size of the wings affect how the rocket flies? Prediction: If we use bigger wings, then the rocket won't travel as far because of the air resistance. Distance flown depends on wing size Size of Wings (cm)

Trial 3

Kelsey, Kelsey, Marcie

Controlled Variables: Bottle size, amount of water in bottles, type of wings, angle, where we shoot it Materials: 2 liter bottles, 20 ounce bottles, duct tape, cardboard, markers, water, launcher Procedure: 1. First take the paper off the bottles and rinse them out 2. Then fill the big bottles with 750 ml of water and the little ones with 150 ml of water. 3. Cut the different sized wings to the size they are supposed to be (12x16, 10x10, 10x15, 10x4 cm). 4. Cover the wings with one layer of duct tape 5. Attach them to the big bottles, 11.3 cm apart 6. Attach the little bottle to the bottom of the big one with duct tape Conclusion: Our conclusion is that when we use 10x10 cm wings, then it will fly the farthest. When we use 12x16 cm wings, it won't fly as far. We could have made sure that the weather was the same every day and that there wasn't any wind, or the wind was the same speed everyday that we launched the rockets. Our hypothesis and question were both wrong and right because the smaller wings, didn't go as far as the smaller wings. But the 10x10 wings are neither smaller or bigger than some of the other ones because both sides are different.
