Final Post!! :)

The rocket bottle lab was a very fun and creative way of learning physics one of our favorite projects ever. As we learned how to create a water bottle rocket, we also learned the physics that went along with it such as gravity, and aerodynamics. During the project we came up with many different ideas with how the rocket would be constructed. Our idea that we agreed upon was to create rocket that had eight small wings that was evenly spaced. We used another soda bottle for our nose cone and tried to cut a trash bag into a parachute. The bigger the parachute the longer the bottle would stay in the air. The only problem with that was when the parachute got bigger it was very difficult to fit in the nose cone. We had some trouble with trying to come up with a way to have that big parachute and have it deploy. Our designs seemed to be very good, but putting it together was the hard part. Our good launches ended up going very high and we think that the height of the rocket was greatly affected by the type of wings we created and how we constructed the rocket with them. We created our wings with a very light piece of wood. Ducking taping the wood kept the wood stable and very hard.

Having a consistent launch every time was very difficult. The wings kept falling off when they hit the ground and sometimes the launches were a bust and didn't go as high as it did before. When we did have a good launch everything was in sync, the timing of the parachute opening and the nose cone falling off was perfect. When we had bad launches it was due to our pumps, and our parachute not opening which was due to construction of the rocket. If we needed to change things we would of probably used a better nose cone and a bigger one. If we had a bigger nose cone our parachute would of been able to fit easier and hopefully it would have deployed. All in all this project was very fun and creative, we should definitely do something similar to this again.
