Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that cocnut juice will get rid of the green slime. Homer decides to check this out by spraying half the shower w/ 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 what was the initial observation? identify the control group independent variable dependent variable what should homer's conclusion be?
Barney aims to know whether coconut juice, as his friend suggested, is an effective treatment for removing green slime from his showerhead. In his experiment, the effect of the coconut juice, the independent variable, on the amount of green slime on his showerhead, the dependent variable, was investigated. He used water as a negative control which is expected to have no effect on the amount of green slime. Because there is no significant difference in the amount of green slime on the side of the showerhead treated with coconut juice and the side treated with just water, the negative control, Homer must infer that coconut juice is not an effective treatment in removing green slimes. There is no evidence to show that his friend's claim is true.
