To kick off this year we did a separation lab today.
Here's how we did it:
We took a small beaker and added 8.85 MG of Pure Sugar, 6.01 MG of our Iron Metal Chips, as well as 6.56 MG of Small Boiling Stones. After thoroughly mixing the elements together, and we mean thoroughly!
We TRADED!
We got Steven and Victor's mixture and had to figure out some way to separate it. After many failed ideas, we decided on the easiest solution. To get the iron filings out we took a magnet to the mixture which pulled all of the filings out. We weighed those and ended up with 3.05 MG of filings. This measurement is not far from the actual 4. 23 MG. After attempting to manually separate the calcium chloride and boiling stones and failing! We were stumped on how to separate the remaining elements, but then Mr. Ludwig gave us an amazing idea: Calcium Chloride is dissolvable in water. The boiling stones are not! We measured the combined mixture and got 20.14mg. By using a water filter paper, a funnel, and a beaker we combined the mixture with water, poured it into the funnel and let it rest overnight. When we came back to class the next day the components were separated and we found out that there was 10.06 mg of the boiling stones and 10.08 mg of sand!
