Transcript of "Sci Meth Intro Audio"

  1. 1. The Scientific Method <ul><li>http://www.virtualsciencefair.org/2004/mart4m0/public_html/process2.jpg </li></ul>
  2. 2. 1. Define the Problem <ul><ul><ul><li>Based on observations & form a question </li></ul></ul></ul><ul><ul><ul><li>Collect existing info </li></ul></ul></ul>
  3. 3. 2. Form a Hypothesis <ul><li>a. A testable explanation to the problem </li></ul><ul><li>b. Cannot be accepted until supported by a large number of tests </li></ul><ul><li>c. May need to be revised or dismissed </li></ul>
  4. 4. 3. Design a Controlled Experiment <ul><li>a. Set up to test hypothesis </li></ul><ul><li>b. Must test only one condition </li></ul><ul><li>c. All conditions are alike except for the variable </li></ul>
  5. 5. Controlled Exp cont’d <ul><li>1. (Experimental) Variable : the one factor being tested </li></ul><ul><li>2. Two Groups: same conditions except for variable </li></ul><ul><li>a) Control Group : not exposed to variable </li></ul><ul><li>b) Experimental Group : exposed to variable </li></ul>
  6. 6. 4. Observations <ul><li>1. record qualitative and quantitative data </li></ul>
  7. 7. 5. Conclusion <ul><li>1. data has value when a valid conclusion can be drawn </li></ul><ul><li>2. Theory : a hypothesis supported by many different exp/long period of time </li></ul>
  8. 8. Observation  Problem Hypothesis Controlled Experiment Results Conclusion Publication/Theory Reject & Revise Hypothesis Other scientists exp & repeat Additional Hypothesis
  9. 9. Example <ul><li>Let’s say you are out fishing. The fish aren’t biting for you, but another guy has them jumping into his boat… </li></ul>
  10. 10. Testing… <ul><li>So, you find out what bait he’s using, and you switch to it… <Good> </li></ul><ul><li>Then you move your boat… <Bad> </li></ul><ul><ul><li>Why is this bad? </li></ul></ul>
