Steps in the Scientific Method

  1. The first step is to come up with a scientific or research question that you are interested in investigating.
  2.  Based on your research question, a hypothesis or an educated guess is formulated.
  3.  The next step is to design and conduct the experiment. A good design should take into account what has been done previously. Thus, a thorough review of methods and results published previously should be undertaken. This will help prevent making the same mistakes and save a lot of time conducting the research.
  4. Perform the experiment/research and collect results and draw conclusions.
  5. If the hypothesis is not supported, then a new hypothesis/research question should be created and a new experiment be conducted.
  6. Ultimately, researchers hope to publish their research in peer-reviewed journals.
