Your experiment tests whether you hypothesis is accurate. It is important for your experiments to be a fair test. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same. You should also repeat your expierments several times to make sure they are accurate. When you observe and record the experiment you want to make careful observations and write down what happens. Once your experiment is complete, collect your measurements and analyze them to see if they support you hypothesis.
The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? Next you have to form a hypotheses. A hypotheses is a educated guess about how things work. A good hypothesis allows you to make a prediction.
The scientific method is a method of research in which a problem is identified
