Experimenting During Class #6

Today in class we made another batch of biodiesel. This time everything went more smoother than last time. When we started the experiment everybody just went to do a job that was open. For instance there was about four people putting the oil into the bottles, and there were two people measuring the sodium hydroxide. The small glass bottles that we used last time to put the methanol and sodium hydroxide in got dirty and people had to clean them out, so we had about three people cleaning them out. The people that got done first were the people who were putting in the oil in the bottles. Our teacher went ahead a took the small glass bottles that were already dry and started to pour the methanol in them. The people with the sodium hydroxide weren't done measuring and took the longest out of all the three stations. After the sodium hydroxide people were done measuring everyone pour the sodium hydroxide in with the methanol and shook the bottle until all of the sodium hydroxide was gone. Lastly when waited in line to get our methanol,sodium hydroxide and our oil to get mixed together. Our teacher shook it 8 times this time. We can also try to test the oil by using a physical property test by it's boiling point or how dense it is.
