The Scientific method is a serious of steps that scientists use to solve a problem. To do the first step of the scientific method you would need to identify a problem by observing things. Then for the second step you will need to make a hypothesis of what is going to happen. Then you would test the hypotheses to see if it is correct. If it's incorrect then you will have to do another experiment, with a different hypotheses. You will have to keep doing experiments until your hypotheses is right. This is the scientific method of solving problems.
For example Aristotle said that heavier objects fall faster than light objects. Then Galileo proved him wrong by dropping a very light object and a heavy object at the same time from the Tower of Pisa. Somehow it ended up that the objects fell to the floor at the same time.
