Hypothesis
If we put 10 grams of cotton balls, hay, and sponges into 4 separate 6L bins filled with 6 cups of water and 2 cups of motor oil , we can see which method takes the most oil off water, then cotton balls will absorb the most oil off of the water.
Variables
Independent Variable: Cotton, Hay, Sponges.
Dependent variable: Amount of oil soaked up.
Controlled Variable: The amount of water and oil at the beginning of experiment , the weight of the objects tested before the experiment (10 grams), room temperature environment, time (5 minutes).
