2. Do Now 1. What do you observe ? 2. Who do you infer is in the control group and why? 3. What are some controlled variables for the two groups? 4. What appears to be the dependent variable ? 5. What could you infer to be the independent variable ? ***Remember, a control group IS NOT a controlled variable.***

3. Week in Advance  Today: Scientific Method Procedure  Tomorrow: Malleable Intelligence and Getting on the A-Train  Thursday: Review Game  Friday: Scientific Method Test

4. Todays Agenda  Do Now  Return Homework  The Most Absorbent  Engrade Slips  Exit Ticket

5. The Scientific Method 1. Question 2. Hypothesis 3. Experiment 4. Analyze Results 5. Conclusion 6. Communicate

6. The Most Absorbent  Keep notebook paper out  Observations and Inferences

7. 1. Question  Does a higher priced brand of paper towels affect their absorbency?

8. 2. Hypothesis

9. 3.Experiment Controlled Variables: Glass, funnel, water Independent Variable: Brand Dependent Variable: Absorbency Experimental Group- More expensive paper towel (Bounty) Control Group - Less expensive paper towel (Sparkle)

10. Analyze Results  What happened?

11. Conclusion

12. Communicate

13. Exit Ticket and Engrade Slips  What are the 6 steps to the Scientific Method?
