Question 1 - 10
• Name the 6 steps of the scientific method.
Answer 1 – 10
• Problem• Information• Hypothesis• Experiment• Results• Conclusion
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?
Answer 1 – 20
• Does Cheer or OxiClean keep white clothes from looking dingy?
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?
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.
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?
Answer 1 – 40
• Load C
Question 1 - 50
• Write a procedure to test to see if OxiClean or Cheer keeps white laundry whiter.
Answer 1 – 50
1. Buy 3 identical white T-shirts2. 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 machine4. Add 1 cup OxiClean laundry detergent5. Wash Load A on warm-cold setting6. When finished, place in dryer until thoroughly dried7. Repeat with Load B (1 cup Cheer) and Load C (no
detergent added)
Question 2 - 10
• What is the definition of an independent variable?
Answer 2 – 10
• An independent variable is one you CONSCIOUSLY change
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.
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
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?
Answer 2 – 30
• The brightness of the laundry
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
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.
Question 2 - 50
• Come up with an experiment about anything you choose and identify the following:– Independent variable– Dependent variable– Control group– Constants
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)
Question 3 - 10
