We repeat steps three and four in the scientific method such as to form a hypothesis and conduct an experiment in order to arrive at the perfect answer to the question and provide a right direction to further scientific investigation and most importantly in order to verify the results. Since different science disciplines have different criteria for determining what good results are. “Practice make perfect” is apparently true for the experimentation in order to develop skills which is necessary to extend established methods and develop new experiments. Lastly, The experiment must also be reproducible so that it can be tested for errors.
