  1. THE SCIENTIFIC METHOD A SERIES OF STEPS USED TO ANSWER QUESTIONS AND SOLVE PROBLEMS ABOUT THE WORLD AROUND US!

  2. TO HELP YOU REMEMBER THE STEPS, REMEMBER THIS: • S • G • F • P • A • D • “SIX GREAT FARMERS PLANT ALL DAY!” 6!

  3. S.G.F.P.A.D. = 6 STEPS TO THE SCIENTIFIC METHOD: • S = State the Problem! • G = Gather Information • F = Form a Hypothesis • P = Perform an Experiment • A = Analyze Data and Results • D = Draw Conclusions

  4. STEP #1: STATE THE PROBLEM • The Problem is usually written in the form of a question! • It is also called the “Purpose” of the experiment.

  5. STEP #2: GATHER INFORMATION • Background information about the problem may be found on the internet, at the library, by talking on the phone or e-mailing experts, and so on.

  6. STEP #3: FORM A HYPOTHESIS • A “hypothesis” is an educated guess about the outcome of an experiment. • The hypothesis may be proven (“true”) or disproven (“false”). It is OK to end up with a disproven hypothesis! • It is usually written as an IF-THEN statement.

  7. STEP #4: PERFORM AN EXPERIMENT • The Experiment is used to test the Hypothesis. • An Experiment is like following a RECIPE, with the Materials as “ingredients” and the Procedure as the “instructions!”

  8. WHO, ME??me? STEP #5: ANALYZE DATA • The Data from an Experiment can include measurements, calculations and observations…the “results” of the experiment. • Most Data are shown in the forms of tables, charts, and graphs.

  9. STEP #6: DRAW CONCLUSIONS • Ask yourself: Was my original Hypothesis proven or disproven? • This is not really the “last” step! New ideas and new questions can lead to future ideas and the whole process begins again! ??????????

  10. WHY IS THE SCIENTIFIC METHOD SO IMPORTANT? • Not only do these steps help us answer questions, but, over time, they lead us to THEORIES and LAWS. • A THEORY is based on ideas that have been tested and shown to be true over and over. • A LAW describes how Nature acts under specific situations (EX: Laws of Gravity) • Both theories and laws can be changed or discarded as we gain more knowledge!

  11. THE GOALS FOR SCIENCE? • Honest experimentation using Scientific Methods. • Sharing of knowledge with other scientists. • Ability to repeat experiments. • Questioning, skepticism, and being open to new findings and ideas. • Self-correction (EX: The Earth is NOT flat!) • PSEUDO SCIENCE
