What is the independent, dependent variable, and control group in this experiement?

Homer notices that his shower is covered in a strange green slime. His friend braney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying hald the shower with cocunut juice and the other with water! HELPP PLEASE!!|||dependent variable: spraying coconut juice


because is the variable that YOU control


the independent one is is what the dependent caused..


the control group is the side sprayed with water..





if u had a new medicine and u give it to only have A and not B, A is the experimental group and B the control group


hope this helps|||The independent variable, teh one you manipulate directly,


(usually the item under test), is the fluid sprayed


for cleaning the slime. - Water vs coconut juice.





The dependent variable is the amount of slime removed.


(This should be as unform as possible.


A better experiment might be to use two parts


of the same wall to get 'equal slime' for the test.)





The control group is the half sprayed with water used as a comparison.





What is missing is a calibrated measurement of the difference.


Maybe Homer could call in Ned Flanders to assign 'cleanily eenily' numbers.
