=1. We started with a mixture of liquids, the color was brownish and opaque. The original sample of the water had a strong odor and was not see through.= =Inside the liquid there was small little molecules of a solid, which we needed to filtrate out. The first filtration we did is the sand and gravel filtration to get rid of the suspension. To do this we poked some holes in a cup and filled it with a layer of gravel, a layer of sand, then a layer of gravel again. After setting this up we filtered our liquid through it. the sand and gravel filter took out the specs of a solid object. Following that we took a dropper and did our best to eliminate all the oil from the top of the liquid to change the chemical property to the least amount of oil possible, which in result raises density. Once we got a good portion of the oil out, and raised the density. we moved onto the last step. We put this element called charcoal into are water to change the physical property. The suspension was still in the water at the moment. . we then filtered through filter paper in a funnel, even though this took much much longer then any other filtration method, it made the water look closest to drinking water. There was a huge physically and chemically change in all these steps.= = = =2. First step, took the solid objects out of the liquid. The second step took most, if not all, of the oil out of the mixture. Last, the filter paper takes all unwanted chemicals, color, and odor out. As we did this process we realized the volume of water got lower and lower. At first it started with 200 ML, and as we went step by step it ended up to 154 ML. That decreased a lot because all the materials in the beginning that were in the water disappeared. In this process the water was getting filtrated.= = = =3. In conclusion all the steps we took were necessary in filtering the compound. Without the gravel filtration the pieces of solid would clog the dropper in step 2, without step 2 the oil would be too thick to filter through the filter paper.=
