In my hypothesis, I predicted that; if laundry soap, vinegar & baking soda, as well as a spoon & a sponge are used to contain and absorb a model oil spill, than 95% of the oil will be contained, while 90% of the contained oil is absorbed. This Hypothesis was not correct because approximately 70% of the oil was contained, and approximately 95% of the oil was absorbed or taken out of the basin. We were able to contain the majority of the oil using the sponge, because the oil was less dense then the water and therefore floated; the sponge was able to move the oil into a corner and contain from the rest of the oil. This allowed a fairly good absorption from the spoon as it was able to scoop out the oil as it was kept in a corner by the sponge, then the density of the oil kept it a float making it easy to scoop out.
We decided upon the 4 items we chose; the spoon, the laundry soap, the sponge and the baking soda and vinegar, for a a lot of reasons. We chose the spoon because we knew the oil would be easy to scoop out because of its low density. We chose the laundry soap because we knew it removed grease and oils and therefore would disperse the oil. We decided upon the baking soda and vinegar because we believed its chemical reaction when mixed would cause the dispersal of oil around it. And lastly we chose the sponge because we believed it could be used to absorb the oil, which although it did do, it turned out to be more useful to move of the oil. All variables were considered as we chose what four items we believed to be the best for the, containment and absorption of the model oil spill. We controlled all the variables and made sure neither the amount of oil or the amount of water was tampered with as these where our two controlled variables. Our dependant variables were the amount of oil we contained and the amount we absorbed and as I said earlier our independent variables were our 4 items of chose for our clean-up of the model oil spill.
I cleaned up the oil spill using, 1 spoon, 1 sponge, 25mL of laundry soap, and 25mL of vinegar and a tsp. of baking soda. The spoon contained 20% of the oil and absorbed 75%. The sponge contained 50% of the oil and absorbed 20%. The laundry soap did not absorb any of the oil and it contained 30% of it however upon mixture the 30% of contained oil just resumed back to its normal position. The baking soda and vinegar (bs and vinegar) was unable to absorb to the oil however it contained 50% of it on either side of the basin, once again upon mixture this containment was diminished and baking soda and vinegar returned to its previous position. In the end approximately 95% of the oil was absorbed and 70% of it was contained.
My experiment was correct because all the variables were accurately controlled. If I were to recreate this experiment, I would not mix in the laundry soap and baking soda and vinegar, as this made resultless effective then the previous successful containment that the individual substance had made. My only detectible error is the mixing of laundry soap and baking soda and vinegar into the oil for the reasons stated above. If this experiment were to be repeated I would probably decide to include the testing of more items in an effort to contain and absorb the oil as this would help get an exact solution to this problem.
