HOMER NOTICES HIS SHOWER IS COVERED IN GREEN SLIME. hI8S FRIEND BARNEY TELLS HIM COCONUT JUICE WILL GET RID OF THE SLIME. HOMER
Orlov [11]

Answer:

INDEPENDENT VARIABLE: COCONUT JUICE

DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME

CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER

CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER

Explanation:

- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.

- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.

- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.

- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.
