You decide to clean the bathroom. You notice that the shower is covered in a strange green slime. You decide to try to get rid of this slime by adding lemonade juice. You spray half of the shower with lemonade juice and spray 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.

Match the variables correctly to the experimental design above.

• dependent variable

• no lemonade juice

• control

• lemonade juice

• independent variable

• green slime
