 Scientific Method Review

  Ask a question to find out more information or to solve a problem.  What does this fossil show?  What kind of medicine will cure a disease? 1. Ask Question

  Find as much information on the problem or question as possible.  You may be able to answer your question with simple research and avoid an lengthy experiment! 2. Do Background Research

  An explanation based on limited information. Must be further researched to determine its accuracy or truthfulness. 3. Construct Hypothesis

  Construct a measurable experiment  Collect Data:  Information such as numbers, images, or words, gathered in an experiment. 4. Test with Experiment

  Conclusion - The result of an experiment, action, or process. 5. Analyze Results/Draw Conclusions

  Report Results  Show Data, graphs etc.  Write explanation  Report - A well-written scientific paper containing a hypothesis, explanation of experiment, all gathered data, and a conclusion of results. 6a. Hypothesis True?

  Still report results!  Go back through the method and try again!  Report - A well-written scientific paper containing a hypothesis, explanation of experiment, all gathered data, and a conclusion of results. 6b. Hypothesis False?
