3. Question 1 - 10 Name the 6 steps of the scientific method.

4. Answer 1 – 10 Problem Information Hypothesis Experiment Results Conclusion

5. Question 1 - 20 I am thinking about switching brands of laundry detergent. Cheer claims to keep your whites looking bright, but I am thinking about switching to Oxiclean. What is a good testable question for this scenario?

6. Answer 1 – 20 Does Cheer or OxiClean keep white clothes from looking dingy?

7. Question 1 - 30 I am thinking about switching brands of laundry detergent. Cheer claims to keep your whites looking bright, but I am thinking about switching to Oxiclean. What could my hypothesis for this experiment be?

8. Answer 1 – 30 If I were to wash something white with dark colors, THEN the one washed with Cheer will stay white BECAUSE Cheer claims it can brighten whites in one wash.

9. Question 1 - 40 To test to see if OxiClean keeps whites looking whiter, I buy 3 white shirts and I throw them in 3 different loads of laundry all containing 5 pairs of dark jeans. I use 1 cup of Oxiclean in load A, 1 cup of Cheer in load B, and no detergent in load C. What is my control in this experiment?

10. Answer 1 – 40 Load C

11. Question 1 - 50 Write a procedure to test to see if OxiClean or Cheer keeps white laundry whiter.

12. Answer 1 – 50 1.Buy 3 identical white T-shirts 2.Fill 3 baskets each with 5 pairs of dark wash jeans (Load A, B, C) 3.Put Load A + 1 T-shirt in the washing machine 4.Add 1 cup OxiClean laundry detergent 5.Wash Load A on warm-cold setting 6.When finished, place in dryer until thoroughly dried 7.Repeat with Load B (1 cup Cheer) and Load C (no detergent added)

13. Question 2 - 10 What is the definition of an independent variable?

14. Answer 2 – 10 An independent variable is one you CONSCIOUSLY change

15. Question 2 - 20 To test to see if Oxiclean keeps whites looking whiter, I buy 3 white shirts and I throw them in 3 different loads of laundry all containing 5 pairs of dark jeans. I use 1 cup of Oxiclean in load A, 1 cup of Cheer in load B, and no detergent in load C. Give at least 3 constants detailed in the above scenario PLUS 2 more things that should also be constant.

16. Answer 2 – 20 In scenario: – Type of shirt bough to test – Contents of the load of laundry washed with the shirts – Amount of detergent added to each load Additional constants: – Settings of the washing machine – If the laundry is dried in the drier or on a clothes line – Size of the jeans washed with the shirts (size of the load) – Brand of the washing machine used to wash each load

17. Question 2 - 30 I wanted to test to see if Cheer or OxiClean were to keep whites brighter. If I were to design an experiment, what would be my dependent variable?

18. Answer 2 – 30 The brightness of the laundry

19. Question 2 - 40 I want to test the battery life of a MacBook Pro versus a MacBook Air. Tell me the following: – Independent Variable – Dependent Variable – At least 3 constants

20. Answer 2 – 40 Independent variable: type of computer Dependent variable: the amount of time before the laptop goes dead Constants: – Size of the computer (13’’ vs 15’’; internal memory of the laptop) – What the computer is doing when testing (streaming music? Browsing the internet? In sleep mode?) – How many windows are open at the time of testing.

21. Question 2 - 50 Come up with an experiment about anything you choose and identify the following: – Independent variable – Dependent variable – Control group – Constants

22. Answer 2 – 50 Sample: I want to see if Tylenol or Advil is faster at relieving headaches. – Independent variable: medication – Dependent vaiable: time it takes for the headache to go away – Control: no medicine – Constants: severity of the headache, the dosage of the medicication, when the medicine was made (expiration dates), type of headache (stress vs dehydration vs concussion)
