  1. Bottles Rocket By: Eileen Broome and Megan Bailey Science Fair Project

  2. Statement of the Problem How does the carbonation affect the height of a bottle rocket?

  3. Project Overview Megan and I are going to launch bottle rockets and see whether or not the one with carbonation will go higher than the one with water in it.

  4. Research • We researched which rocket will go higher • The rocket with soda went higher • We launched both rockets each with three fins

  5. Variables • Independent variable: Cola- millimeters • Dependent variable :Height- feet • Constant variables- type of bottle, type of fin, type of nose • Control group: Water

  6. Hypothesis If we use cola then the rocket will go higher because the carbonation will give more pressure.

  7. Materials • Duct tape,3 bottles (2 L), cola, water, rocket shooter, nose, notebook, camera, bike pump, and clinometer

  8. Procedure • Gather materials • Build rocket- Cover your rocket in duct tape, to make a nose get a cone and a ball of rubber or modeling clay and drop it into the cone ,tape your nose on the top of the rocket • Make rocket launcher- get a pump and a tube and attach them together, get a small part from a water pipe and attach them together • Test hypothesis- by conducting experiment • Collect data- collect average(see below), and height of all the rocket launches • Analyze data • Make graphs, charts, board, etc.

  10. Data/Observations (Analyzes) Quantitative Observation:                     Qualitative Observation: Building:                                                   Building: -We used one roll of duck tape                  - We used black Duck Tape -We used one long cardboard like tube     - We had a cardboard tube on each rocket for both of the bottle rockets.                    - We stripped our bottle of its label -We had (2) 2L bottles                              - We had a wooden on the top of our nose Launching:                                                 Launching: -We shot each bottle rocket off once but -The Cola went higher than water used (3) timers.                                         - The Water went before Cola Averaging: -The average time for water is  2.53666666666667 -The average time for cola is 5.553333333333333

  11. Conclusion Our data does prove our hypothesis. The rocket with the carbonation definitely went higher than the rocket with water in it. I think the rocket went higher because there was carbonation and it egged on the air and it expanded the bottle so it had more will to release itself.

  12. Possible Experimental Errors • There could have been problems in the nose. The duct tape could have weighed the rockets down. There could not have been the right amount of pressure. The mass in the nose couldn’t have been enough mass. The rockets could have been launched differently.

  13. Applications and Recommendations • Suggestions to make the experiment better would to have pump not just a bicycle pump. It would make it a lot easier. I would also try to do it on another day. It was a little windy the day we did it so that could have affected out times. Something else we could have improved was the identity of each rocket to make it more like the other. • Something weird happened after we did our experiment. Well, we had extra time and decided to launch another bottle rocket with nothing on it but is had soda that had not been poured out yet. When we launched it, it went higher than the others. So that would be a good experiment was it the less mass that made it go higher or the still fresh soda?
