  3. 3. The Scientific Method Steps <ul><li>1. Identify the Problem </li></ul><ul><li>Gather Information </li></ul><ul><li>Form a Hypothesis </li></ul><ul><li>Experiment </li></ul><ul><li>Record & Analyze data </li></ul><ul><li>Communicate the Results </li></ul><ul><li>REPEAT!! </li></ul><ul><li>Video 1 ( 2 min.) </li></ul><ul><li>Video 2 (21 min.) </li></ul>
  4. 4. A Message Traveling Along Nerves <ul><li>Problem: How much time does it take information to travel from your eye through the brain, and then to your hand? </li></ul><ul><li>Hypothesis: I believe it will take ____ seconds for information to travel from my eye to my fingertips. </li></ul>
  5. 5. <ul><li>Experiment: </li></ul>Average score: _______ Total (add all 3) Trial #3 Trial #2 Trial #1 Distance Ruler Fell (cm) Trial Drops
  6. 6. <ul><li>Conclusion: The time for a “message” to travel from your eye through the brain to your hand is equal to _______ seconds. </li></ul>
  7. 7. Rules & Terms of the Scientific Method <ul><li>When writing the hypothesis use the: </li></ul><ul><li>If __________, then ___________. </li></ul><ul><li>(Independent Variable) (Dependent Variable) </li></ul><ul><li>Variable: factors in an experiment that can change or being tested. </li></ul><ul><li>1.

  9. 9. Graphing Rules to Remember <ul><li>Appropriate title </li></ul><ul><li>Use a consistent scale </li></ul><ul><li>Correctly plotted </li></ul><ul><li>Label both axis correctly & with units </li></ul><ul><li>NO NAKED NUMBERS!! </li></ul>
