The FINAL step in the scientific method is to have a conclusion. All of the answers that you questioned are answered and you figured out if you're hypothesis was either right or wrong!
In the fourth step, you write down your results from the experiment. You would also write results again if you repeated your experiment several times.
The third step, you have to experiment with the materials you have to test your hypothesis.
In the second step you have to to come up with a hypothesis which in other words, make an educated guess. In your hypothesis it has to be testable and it's completely fine if the hypothesis is wrong.
The first step in a scientific method is to have a question or something you want to experiment on because how would you do an experiment if you don't have a topic or question to test.
