The first step of the scientific method is to observation. It is the step where you research everything you can about your problem.
The second step is to form a hypothesis. It is a general statement based on research and observation.
The third step is to make a prediction. It is what you think the outcome of the experiment will be.
The fourth step is to experiment. This is where you will test your hypothesis.
The fifth step is your conclusion. If your hypothesis was right, then this is the last step. If your hypothesis is incorrect, then you must form a new hypothesis and repeat steps 2-5.
