  1. Scientific method

  2. SCIENTIFIC QUESTION #1. Scientific Question • A testable, scientific question based on observations. • How long does Old Spice Odor Blocker body wash eliminate odors?

  3. #2. Hypothesis • A prediction that describes the relationship between the variables. prediction variables

  4. Which Hypothesis is Best? • Old Spice Odor Blocker Body Wash will eliminate odors for 16 hours. • Old Spice Odor Blocker Body Wash will eliminate odors. • Old Spice Odor Blocker Body Wash will work best.

  5. #3. Experimental design

  6. INDEPENDENT Independent variable • What is being tested or compared in an experiment. • The cause. • The before. • YOU Control it! cause.

  7. Old Spice Odor blocker • What is the Independent Variable? • Type of body wash • Odor • Showers

  8. Dependent variable • The outcome of the experiment – what is being measured. • The effect. • The after. • YOU Measure it outcome measured. after.

  9. Old Spice Odor blocker • Dependent Variable: • Body odor • (time to smell!!)

  10. VARIABLES Constant variables • Things that stay the same throughout the experiment. • same

  11. Old spice odor blocker • What might we keep the same?

  12. CONTROL Control group • Thebaseline group. • Does NOT have the experimental treatment. baseline

  13. Old Spice Body blocker • This group would have NO body wash. • Instead, they would just wash with water. Yum NO body wash

  14. Experimental group • The group or condition being tested. condition

  15. Old spice body blocker • This group would use the Old Spice body wash.

  16. #3. Experimental design continued • List of materials required • Numbered, step-by-step directions/procedures materials procedures

  17. #4. results RESULTS • Organize collected data in a properly labeled data table. • Choose an appropriate graph for collected data. • Create the graph. Properly label the graph. • Analyze the data – identify trends/correlation (positive, negative, orno relationship) from data obtained in the experiment. properly graph label Analyze no

  18. #5. conclusion • 5 sentences: • - This experiment investigated … • - The hypothesis stated … • - According to the data the hypothesis was … (supported or not supported) • - I know this because … • - This is important because …
