In my hypothesis I stated that I would absorb 95% of the oil and contain 100&% of the oil. What actually happened was that I contained 60% of the oil and absorbed 75% of the oil. I predicted that I would be able to clean up much more oil than did. I had lots of faith in the products that I used, when in reality, the products that I picked were not as effective I as had thought.
In this experiment, I cleaned up a crude oil spill, using 5 paper towels, 10 cotton balls, 25mL of dish soap, and 25mL of vinegar and baking soda. I did this discover how hard it is to clean up an oil spill when you have constraints. My independent variable was the materials used for absorption and containing. Those materials were 5 paper towels, 10 cotton balls, 25mL of dish soap, and 25mL of vinegar and baking soda. Our dependant variable was the percentage of oil contained and absorbed. Finally, my controlled variables were, the basin, the amount of water, the amount of crude oil and the amount of materials used.
When I clean up the oil spill I used 5 paper towels, 10 cotton balls, 25mL of dish soap, and 25mL of vinegar and baking soda. The paper towels absorbed 20% of the oil and contained 90%. The cotton balls absorbed 40% of the oil and contained 10%. The baking soda and vinegar did not absorb any of the oil, and it did not contain any of the oil, in fact, it did the opposite by spreading the oil out more. The dish soap did not absorb any of the oil either. However, it contains 70% of the oil, while also condensing it into larger blobs.
My experiment was a valid experiment because all the variable were under control. I would probably add more materials to the list so that you could clean up the oil spill faster. Also, be able to use more materials. Some of the materials I would add are a filter, a bowl and finely woven net. I did not identify any major problem other that lack of resources, as I stated before. Also, I do not believe there was any source of error. If this experiment was repeated you could test different types of oil and see if they reacted to the substances differently than crude oil.
