a strange green slime. his friend barney tells him that coconut juice will get rid of the green slime. homer decides to check this out by spraying half of the shower with coconut juice. he sprays the other half of the shower with water. after 3 days of \treatment\ there is no change in the appearance of the green slime on either side of the shower. identify the- 7. control group 8. independent variable 9. dependent variable 10. what should homers conch be? 0. what was the initial observatio

Explanation:

7. Control Group

The control group in an experiment is the group that does not receive the experimental treatment and is used for comparison. In Homer's experiment, the half of the shower sprayed with water (instead of coconut juice) is the control group, as it provides a baseline to compare the effect of coconut juice.

The independent variable is the factor that is manipulated in an experiment. Here, Homer manipulates the substance used to spray the shower (coconut juice vs. water), so the independent variable is the type of liquid sprayed (coconut juice or water).

The dependent variable is the outcome being measured, which depends on the independent variable. In this experiment, the appearance of the green slime (whether it changes or not) is what's being observed, so it's the dependent variable.

Answer:

The half of the shower sprayed with water (the group not treated with coconut juice)

8. Independent Variable
