scientific method [FYI]

In the scientific method, you go through the following steps:

  1. You make observations.
  2. You develop hypotheses to explain these observations.
  3. You suggest experimental ways to test these hypotheses.
  4. You predict the results of the experiments.
  5. You run the experiments.
  6. You compare the results of your experiments to your predictions.
  7. You publish all your results.
