Seven

Group Seven: Aaron + Kristina

1) Describe the type of experiment/demonstration your group will be researching and conducting.

Burning Money Chemistry Demonstration
This is a neat 'magic trick' that illustrates the process of combustion, the flammability of alcohol, and the special qualities of the material used to make currency. A combustion reaction occurs between alcohol and oxygen, producing heat and light (energy) and carbon dioxide and water. C2H5OH + 4 O2 -> 2 CO2 + 3 H2O + energy When the bill is soaked an alcohol-water solution, the alcohol has a high vapor pressure and is mainly on the outside of the material (a bill is more like fabric than paper, which is nice, if you've ever accidentally washed one). When the bill is lit, the alcohol is what actually burns. The temperature at which the alcohol burns is not high enough to evaporate the water, which has a high specific heat, so the bill remains wet and isn't able to catch fire on its own. 2) You may add text, images and information you plan to add to **__your group's__** presentation. 3) There is also a "Discussion" area where you might send messages to each other and reply. Please keep this information related to your topic. 4) Each day we are in the lab, you are REQUIRED to make a "comment" in the Discussion Area telling YOUR FIRST NAME and exactly what you did on your project FOR THAT DAY, what information (in general) you added to your group's wiki or how you contributed to the group's project. THIS IS HOW YOU WILL RECEIVE DAILY PARTICIPATION POINTS when we are working in the computer lab. IF YOU DO NOT ADD A COMMENT WITH YOUR NAME, you will not receive your daily points. 5) You may let me know confidentially if ANYONE in your group is not doing their fair share. I WILL NOT share this with anyone. I will check to see what that person is actually doing and may take away points or put that person in a group by themselves if I think is it necessary.
