Steps Of The Scientific Method

Developing good science fair projects depends on following these steps.

State the Purpose

  • What is your topic...the question you want to answer?
  • Research your topic to learn more about it.


  • Make a guess about the answer to your question.
  • What you think is true based on the topic research you did.
  • When you state your hypothesis it must be something that can be measured in experiments or data you collect later.


  • Test your hypothesis.
  • Do an experiment to see if your hypothesis is true or false.


  • Write down your observations and data you collect in a journal.
  • Photograph the steps in testing your hypothesis if possible.


  • Look at the data and results you got from the experiments.
  • Are your results conclusive or uncertain?


  • What did your results tell you?
  • Did your experiment prove your hypothesis true or false?
  • Do you need to repeat this project to be sure of the results?
  • Can someone else repeat your procedures and get the same results?
  • List any problems you ran into doing this project.
  • Would you do anything different if you did this project again?

The next step after you finish the experiments for your project is to write a project report on it. Good luck with your project and remember, all great science fair projects use the scientific method.
