Homer Water Rocket Hypothesis

In the movie, Homer did not want to go into coal mining like his father had. He was fascinated when he saw a rocket go into space at night and he wanted to do the same thing. He became fascinated in rockets and wanted to build them though his father told him not to. He followed what he wished for and he ended up getting the right team and all the needed parts for the rocket. He ended up winning the science fair and getting a scholarship to college so he didn't have to work in the mines. The rocket was a great success and he was famous for his rocket and what he had done/gone through to build it. The rockets purpose is to go into space or just very high in the air. It was built to go extremely high. With the special metal and fuel that …show more content…
They want a successful launch and know that they need to make changes in order for that to happen. They do this by changing materials they use, the length of their rocket, and changing the fuel they use in the rockets.
The hypothesis was that the rocket would go 20,000 ft in the air. The rocket ended up going 23,000 ft. This shows that their hypothesis was met and the rocket went higher than they even hoped that it would go. Thus proving the hypothesis of the rocket and the purpose of the rocket. The rockets early on were exploding before reaching the height wanted. My hypothesis is that if they need to change the design of their combustion chamber. Then the rockets would be able to be successful in flight without …show more content…
The independent variable was the metal type and fuel that they used in the rocket launcher. The dependent variable was the whole rocket launch because the rocket launcher acted on the rocket making the rocket blast into the air.
The experiment was in a controlled area that was flat and in the middle of the woods. They were eight miles away from the town. At every launch there was calm weather.
The boys used different metals which had different melting points that would be stronger to keep the rocket together better.
The materials they used were the fuel type which was alcohol or 'rocket candy'. The cylinder was made out of metal and had a metal nose cone. The two wings (or vanes) were at the base of the rocket. The procedure that the first few rockets failed to get off the ground became a case of trial and error. Later launches were almost all successes they ended up learning from their early launch failures.The equations S=1/2at^2 and v=at were used to calculate the altitude,velocity,and the distance the rocket will
