Description of final design...
- Both my partner and I made separate rockets. The design for mine is very simple. It consisted of a Neuro Bliss bottle with the pointed cap taken off the top and used as the nose cone. I put a weight ( a candle lid) in the nose cone so the rocket wasn’t so light. The fins were made of a waxed foam board cut into what looked like shark fins
- Our testing variable was the amount of water (fuel) we used. We chose this variable to see if the rocket would go higher with more fuel, or if the extra weight would slow it down.
- Our question was, ‘Will more fuel make the rocket go higher?’
- Hypothesis: If there is more fuel in the rocket then it will go higher because more fuel means more water being forced out and propelling the rocket up.
- Procedure:
- My partner and I only tested our variable by filling our rocket with a differing amount of water each time we launched. We used intervals of twenty-five mL of water. We started with 250 and worked our way up to 275 at which was going to be out final launch. Unfortunately because of a mix of conflicting schedules and procrastination we were unable to get more launches in. Our plan was to launch 5 times and collect those data points, but them into a graph and conclude if our hypothesis was correct. If the rocket went higher when it had more fuel.
