  1. Identify the Controls and Variables With the Simpsons

  2. Smithers • Identify the • Control Group- • Group B with no juice. • 2. Independent Variable- • Group A with special juice. • 3. Dependent Variable- • Amount of papers stapled. • 4. What should Smither’s conclusion be? • The special juice did not make a difference. • 5. How could this experiment be improved?

  4. Krusty • 11. Control Group- • Subject A with the original itching powder. • 12. Independent Variable- • Subject B with the new itching powder. • 13. Dependent Variable- • The amount of itching time. • 14. Explain whether the data supports the advertisement claims about its product? • Since Subject B itched for 45 mins which was 15 mins longer than Subject A with 30 mins, the new powder does make you itch longer. However, it does not provide 50% longer lasting itches. OR 50% of 30 minutes is 15 mins. 30 mins to 15 mins. is 45 mins. So the experimental powder is better.

  5. Lisa • Control Group- • 5 days of hair length before Roogti. • Independent Variable- • Roogti Hair product • Dependent Variable- • Hair length growth • Procedure- • Measure hair length for 5 days. • Add 1 oz. Roogti to hair. • Measure hair length • Repeat steps 2-3 for 5 days total.
