Controlled variables: same measuring utensil same person pulling the string same bottle Materials pop bottles ( 2 liter and 20 oz.) duct tape cardboard water Procedure: Tape the bottom of a 20 oz. and a 2 liter bottle together with duct tape. Then cut three wings out that are 10 by 5 and cover them with duct tape so they are water proof. Then put the 3 wings in the middle of the 2 liter bottle and space them out equally. Then put 100 ml in the nose part or the 20 oz. bottle. Then you put the amount of water that you need to fill out the data table above. Then you put it on the shooter thing and measure how far it went for each amount of water. You do this for each amount of water that you do. Conclusion: From the data that we took our procedure was wrong because we thought that 400 ml would make it go farther but it is actually 600 ml of water that made it go farther. Therefore our hypothesis was wrong. If we would do this again we would make quite a bit of changes, we would make sure we had the right amount of water, make sure the rocket was placed on the shooter right, and make sure our wings and bottles are on right and won't fall off. We would do all of these things if we had more time
