Read the following experimental data carefully and answer the following questions (#’s 49. – 51.).
In the laboratory, brown mice usually gain weight at a temperature of 55oC. A scientist wanted to determine if brown mice would gain weight faster or slower when the temperature was dropped to 25oC. The scientist performed an experiment and recorded the following data.
Weight gain of brown mice at 25 C:
Time(Hours) / 0 / 2 / 4 / 6 / 8 / 10 / 12 / 14 / 16 / 18
Weight gain of brown mice / 1 / 4 / 20 / 38 / 90 / 150 / 220 / 350 / 430 / 550
Weight gain of brown mice at 55 C:
Time(Hours) / 0 / 2 / 4 / 6 / 8 / 10 / 12 / 14 / 16 / 18
Weight gain of brown mice / 1 / 26 / 74 / 170 / 330 / 550 / 600 / 650 / 665 / 670
49. Identify the statement that would be an appropriate hypothesis for this experiment.
50. Identify the independent variable in this experiment.
50. Identify the control group in this experiment.
51. Based on your data, what was the scientist able to conclude from his experiment?
Use the following to answer #’s 52-57.
Bubble Time
Patrick loves bubble gum and would like to be able to blow bigger bubbles than anyone else in Bikini Bottom. To prepare for the Bikini Bottom Big Bubble Contest, he bought five different brands of bubble gum and needs your help to find the brand that creates the biggest bubbles. Write an experiment to test the bubble power of the bubble gum brands and help Patrick win the contest.
