Big Idea- How will the way the rocket is made and how much water is in it effect what the rocket will do.
Objective- Keep the rocket in the air the longest
Materials-
2 2-liter bottles
1 golf tube
1 role of duct tape
1 board of cardboard
1 air compressor
1 launching platform
1 stopwatch
3 angle guns
Prediction- I think by placing everything on straight and by putting 750 ml of water into the rocket it will go the highest.
Plan- Cut the top off of one two liter bottle at the point that it stops curving and turns into a cylinder. Tape the cut [art to the bottom of the whole roket so that it fits snuggly. Tape the golf tube to the bottom of the bottle and make sure that it is secure. Cut four even wings out and tape them onto the bottle spread out evenly.

We have the trial on the left for our 8 different launches. Next in the columns we have how high each launch went. Next we have the time aloft. Next we have how stably the rocket was launched into the air. Next how soft the landing was. Nest was how much water we used.Lastly we have if it was windy and the weather.
This project works by building a rocket that will be placed onto a stand to be launched. To build the rocket you will have to use duct tape, 2 liter bottles, and golf tubes. The rocket will have water in it to be pressurized into the bottle to allow their to be fuel for the rocket. The launcher pumps the air into the water and will release the rocket when you pull the string to allow the rocket to pull itself away from the launcher and into the air.
The best way to do this project it to have a straight golf tube and secure it to the bottle with duct tape so it won't move. Add four wings that will be duct tape to the side of the base of the rocket at even intervals and spray paint the rocket so it will look cool. Add water based on how much your rocket weighs if it weighs more add more water, if it wieghs less add less water

If too little water is used then not enough force will be exerted. If too much water is used then the rocket will be too heavy annd will not fly.
The rocket must have no air leaks or not enough pressure will build and the rocket won't go anywhere.
The rocket must have a central point of mass in the middle of the rocket or else the rocket will spin as it launches due to weight distribution.
The more weight in a rocket the more water is needed to lift the rocket off the ground.

- Acceleration due to pressure acting against the launch tube. (This is not present if a launch tube is not used)
- Acceleration due to the reaction force of the water being ejected.
- Acceleration due to the reaction force of the air being ejected.
- Coast phase (ending at apogee, the highest altitude reached), which is the longest part of the upward flight. The acceleration phases using just the open neck of the bottle as the nozzle are in milliseconds.
- The recovery phase where the rocket returns to earth after reaching apogee.
