Student Demonstration Project 0708-

In the 2007-2008school year I created a quarter project for my chemistry students where they had to research and present a chemical demonstration. I did this for several reasons: first it got me both a lab-type and partner opportunity in one project, next it gave the students and me a chance to see some demonstrations that don't really fit into the curriculum, and finally I wanted them to better appreciate the work that I personally put into doing my demonstrations. Overall the project was a success and we all enjoyed the new demonstrations. The project has been slightly modified, but has become a permanent part of my curriculum. In these videos I've tried my best to film the performance of the demonstration. The explanation of it was given by the students to their peers in a lecture format as a part of the project, but has not been filmed. I will do my best to explain briefly how the demonstration works, but feel free to ask questions. In this demonstration two students do two simultaneous reactions to create: chlorine gas and acetylene gas. Then in a third reaction the two gases react together to create underwater fireworks.

By the time I filled my graduated cylinder to test my final gravity, I had already started transferring the beer into the bottling bucket that contained the priming sugar. So, when I found out the gravity was 7 points higher than it should be, there was no stopping. I was lucky, and when the weather turns cool next year I'll remember to either heat the room with my fermenters, or to swirl them regularly and give them more time.
