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

Question 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.

Browsing the internet? In sleep mode?) – How many windows are open at the time of testing.

Question 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)
