When creating and running an experiment it is important that the scientific and research methods are followed. The first step is to form a research question that you can test. The second step it to form a hypothesis. A hypothesis is what you propose the answer to the question will be. Next you will want to design a way to test your hypothesis. This typically includes choosing and identifying the variables that you will test to prove or disprove the hypothesis. These are called the dependent and independent variables.  Next you will run the experiment. Finally you will report the results of the experiment. This will include running any statistical analysis, defining who the subjects and research methods were as well as any weaknesses that your research design may have. You will include the results of your experiment and if your hypothesis was proven or disproved here.
