  1. Scientific Method

  2. Steps in the Scientific Method REVIEW! • Question • Hypothesis • Design Experiment • Do Experiment • Data Collection • Conclusion • Retest!

  3. Observations- Review • Gathered through your senses • A scientist notices something in their natural world

  4. Hypothesis • A suggested solution to the problem. • Must be testable • Sometimes written as If…Then… statements • Predicts an outcome • I think that…..

  5. Experiment • A procedure to test the hypothesis.

  6. Experiment Variable – factor in the experiment that is being tested

  7. Experiment A good or “valid” experiment will only have ONE variable that changes!

  8. Scientific Experiments Follow Rules • An experimenter changes one factor andobserves or measureswhat happens.

  9. Data • Results of the experiment

  10. Data • Must be organized • Can be organized into charts, tables, or graphs

  11. Conclusion • The data obtained from the experiment to support or disprove a hypothesis

  12. How can we solve a problem in science? 1) Identify a Problem/Question 2) Make/State Observations about the problem 3) Form a Hypothesis about the problem 4) Design an Experiment to test the hypothesis 5) Collect Data (results) 6) Form a Conclusion 7) Retest..Repeat the experiment again to see if you get the same results
