  1. Unit: _Exp. Design____ THE SCIENTIFIC METHOD & EXPERIMENT DESIGN What are some key elements of sci. method that come to mind? 10

  2. Warm-Up 7/29/2014 Which of the following steps in the scientific method was represented by the “Easter Bunny”?

  3. Parts of a VALID experiment - Question - Hypothesis - Independent Variable - Dependent Variable - Control - Constants - Repeated Trials 12

  4. Vocabulary Terms • Variable Factors that change in an experiment. 13

  5. Vocabulary Terms • Independent Variable - The variable that the experimenter purposefully changes/manipulates. • Dependent Variable - The variable that changes as a result of the Independent Variable. (DV gets measured.) 14

  6. Vocabulary Terms • Control -The normal situation (Ind. Var.) left unchanged. Used to compare effects of the IV when changed. Constant -Every other factor in the exp. that is not a variable. 15

  7. Vocabulary Terms • Repeated Trials -The number of times the experiment is repeated. -The more the better. 16

  8. Experimental Design • Problem: The effect of the IV on the DV. -The effect of medicine dosage on blood pressure. • Hypothesis: If…then…statement. -If medicine dosage is related to blood pressureandmedicine dosage is changed, thenblood pressure will change. 17

  9. Experimental Design • IV= -dosage. • DV= -blood pressure. 18

  10. Experimental Design • Control: -placebo, no medicine given. • Constants: -type of medicine -gender, age -diet -what else? 19

  11. Experimental Design • Done after the experiment is complete: -Analyze/Infer- What did the data show? What was learned? What other questions came about? 20
