Conclusion
In Conclusion, out of all the materials, the sponge absorbed the most motor oil out of all the materials which include: Cotton balls, hay, and the sponge itself. In our hypothesis we stated that we thought the cotton balls would absorb the most oil as they are usually very absorbent. In that assumption we were wrong. The sponge collected the most oil because it was more absorbent than the cotton as it has a larger space between fibers so it can absorb more oil in each piece and it had a larger surface area, therefor collecting more oil.
Our independent variables were the hay, cotton balls and sponges. Our dependent variable was the amount of oil soaked up by the tested materials. We tested a control which had only water and oil in it to make sure nothing went wrong in the experiment.
In the end, sponges soaked up the most oil off of the water. So, if you were to have a oil spill and have the materials above, the sponge would be the most affective in cleaning up the oil
