In a scientific experiment you have your hypothesis, experiment, analysis, and conclusion. To start with, the hypothesis is what your trying to find out. This will be the focus of the experiment and what you need to think about while you are conducting the experiment. Your experiment is the main part, this is where you are going to test you theory during many trials. It is always a good idea to look at the results of other scientists experiment to get an idea of what you need to do and what to expect. When it comes to the analysis you are taking a look at the results of your trials. Seeing these results will help you form your conclusion which is assessing your information and finding out if you hypothesis was correct or not. In the case of the Mythbusters video their hypothesis is if a person can exert enough force then they will be able to make a 360° rotation around the swing set and not fall off. In this experiment their independent variable was the degree to which they were able to propel the swing. On the other hand the dependent variable is the amount of force exerted and the only controlled variable is the type of swing being used. In their first trial they had a girl using her body strength to propel herself. She was not able to make it the full 360° but at her peek she had her swing horizontal. In the next trial they did not use they same person, this time they used a male that was heavily padded and instead of having him use his own body strength they had two people pushing him. He was also unable to make it the full 360° but got his swing close to horizontal. For the last trial they used a 65 pound doll and then reduced the length of the chains to half the size using two people to push her. She also was unable to make the 360° rotation. In the analysis they realized that they were not able to exert enough force but they still wanted to figure out if it was possible. They made a model of the swing set that was 1/6 of the size and tested it out. They figured out that it is possible but the force that they would have to use is beyond anything that they could do with their own body strength. This draws their conclusion for them and proves their hypothesis wrong. Even though they went through all the steps of a scientific experiment they still had a couple flaws. For example they should have used they same person so they had the same weight on the swing and just changed how the force was being exerted either using their own body strength or having people push them. Another flaw is seen when they shorten the chain because it is different in the other two trials when that should be one of the controlled variables.
