Explanation:

6. What was the initial observation?

The initial observation is what Homer first noticed about his shower. From the text, it's that his shower is covered in a strange green slime.

In an experiment, the control group is the group that does not receive the treatment (the independent variable) and is used for comparison. Here, the part of the shower sprayed with water (instead of coconut juice) is the control group as it's the group without the coconut juice treatment to compare with the group that got coconut juice.

The independent variable is the factor that is manipulated or changed in an experiment. In this experiment, Homer is manipulating the type of liquid sprayed (coconut juice or water), so the independent variable is the liquid used (specifically, the use of coconut juice as the treatment; more precisely, the type of liquid sprayed, with coconut juice being the variable being tested against water).

Answer:

Homer's shower is covered in a strange green slime.
