Scientific method steps.

    1. Make observations:

You may think the hypothesis is the start of the scientific method, but you will have made some observations first, even if they were informal.

 

    2. Propose a Hypothesis:

It's easist to test the null or no-difference hypothesis because you can prove it to be wrong. It's practically impossible to prove a hypothesis is correct.

   3. Design an Experiment to Test the Hypothesis.

   4. Test the Hypothesis.

   5. Revise the Hypothesis.
