Hypothesis
If we use dish soap, vinegar and baking soda, a sponge, and cotton balls to clean up a simulated oil spill, then we will be able to contain 80% of the oil and absorb a total of 85% of the oil. The sponge would work best absorbing the oil and the dish soap would work best containg
Independent Variable:
Materials Used (25mL dish soap, 25mL vinegar and baking soda, 1 sponge, 10 cotton balls)
Dependent Variable:
Amount of oil absorbed and contained
Control Variables:
Size of washbasin
Amount of water in wash basin
Amount of oil added
Type of oil
Quantity of clean-up materials used
Densities of the water and oil
Temperature of the room
