__Analysis __
I apologize for the lateness of this, Mrs. Pugliese, as I could not find the wiki that we had used... And I also kind of got caught up studying for the big test we had today, so I forgot to ask about the name of the Wikispaces. My sincere apologies!

At the beginning of the process, the water sample we used was a dark brown, maybe greenish type of liquid. The top had a slightly lighter color liquid, which turned out to be oil. Small particles and large particles alike rested in the middle and bottom of the sample, which we had poured into a beaker. After smelling the sample, we felt as though it smelled of garlic, which we concluded to be in the liquid also. Using an extracting tool called a //pipette//, we began the lab by taking out the top layer of liquid, which was separated from the water part. After using the pipette, there was no oil left, which advanced us to the next step of the process. From there, we took a Styrofoam cup, added a layer of gravel, then sand, and then gravel again. This step, named //sand-gravel filtration//, aided in the process of cleansing the water because the larger particles that were in the liquid became trapped in the filter. After that, we moved to the next step, which was filtering more of the impurities through //charcoal.// The first thing we did was mix a charcoal powder type of substance into the water, which made it turn black. Later on, we took filter paper, folded it, and put it in a funnel that rested on a ring connected to a ringstand. From there, we poured the charcoal water through the filter and the funnel into a clean beaker to make sure that there were no problems in our lab. After a long time of filtering the water using the filter paper, we managed to get an almost entirely pure looking beaker of water, which proved that the steps that we used, although some were not too efficient, were able to remove certain impurities from the water, although there were definitely some left over. To fix this though, we would have to go further into the lab and actually boil the water to make sure that most impurities were removed.
