1. Fill a beaker with 500 mL of water.
2.
3. Place the beaker in the freezer.
4. After the water freezes, place the beaker on the balance and measure its mass.

Derrick just got home from playing soccer on a muddy field. He is curious how different brands of laundry detergent compare in removing mud from clothes, so he sets up an experiment.

In one laundry load, he puts his muddy socks with Brand A detergent. In the next load, he puts his muddy jersey with Brand B detergent. In the final load, he puts his muddy shorts with Brand C detergent.

Afterward, he noticed that the jersey came out the cleanest. He concludes that Brand B is the best detergent for removing mud from clothes. Is his conclusion valid?

A. No; there were too many variables in the experiment.

B. No; Derrick was biased toward Brand B.

C. No; there were too many controls in the experiment.

D. Yes; the experiment was set up correctly.

Answer 93

Or d

Answer 94

Or c
