What are the steps of the scientific method? - Answer- 1. Make *observations* 2. Formulate a *hypothesis* 3. *Devise* a testable prediction 4. *Conduct* a critical experiment 5. *Draw* conclusions and make *revisions* Theory - Answer- a hypothesis that has withstood the test of time and is unlikely to be altered by any new evidence, broader in scope than an hypothesis. Hypothesis (how can a hypothesis become a theory?) - Answer- a proposed explanation for a phenomenon, it can become a ...
