When we first started our lab we extracted the oil from our __compound__ and we did this with a pipet. We used the pipet to suck the layer of oil that was sitting on top of our sample so that chemical property would be one step closer to being purified. Physical Properties include the sand and the gravel although the gravel is heterogeneous with the sand. By removing the oil we changed the density of our sample. In the second step, we used a straightened out paper clip to poke several tiny holes into the bottom of a styrofoam cup. Then we added the gravel and and the sand to sandwich it inside the cup. Next we poured our sample into the sand - gravel filter and it filtrated out though the bottom of the cup and into beaker. In the beaker we now have our __filtrate__. We tossed out the sand - gravel filter and measured the filtrate in a graduated cylinder. Next, we put a spoonful of charcoal powder in our sample and stirred it with a a stirring rod so that the charcoal would be even though out our sample. We then folded a piece of filter paper and put it in the funnel. Then, we put the funnel in a beaker and carefully suspended it on the Bunsen burner. Next, we slowly poured the sample into the funnel to go through a chemical change. Finally, we measured the filtrate in a graduated cylinder for a second time and the final result of our solution came to the element water. The final product is composed of water molecules and purified water. This final mixture was the solution.
