Question
Our question is: What materials can we use that will be the most effective to clean up the oil?
Hypothesis
Our hypothesis on how to best clean up an oil spill is as follows. If 1 sponge, 10 cotton balls, 1 spoon, and 5 paper towels are used then 90% of the oil will be absorbed and 60% will be contained.
Independent Variable: The materials used to clean the oil.
Dependent Variable: The amount of oil left.
Controlled Variables: The amount of oil to start with, and the size of the washbasin.
