Fermentation is an energy producing process that does not require oxygen to take place. It's anaerobic in nature. Bacteria, yeast, and even human cells use fermentation to create energy in the form of ATP. Dr. Kiki from Food Science talks about ho...w fermentation works, not just in creating alcoholic beverages that people enjoy, but also inside humans. Watch as she whips up some home made ginger ale at the end of the episode! Run time 05:52.

Why do people eat mashed potatoes on Thanksgiving Day but not mashed paper towels? That’s not such an odd question from a chemistry standpoint because potato and paper are almost as similar as two peas in a pod in terms of the carbohydrates they cont...ain.
For the answer to that and other topics that could spark dinnertime conversation, the American Chemical Society (ACS) is offering an addition to the holiday menu: A special video on the chemistry of Thanksgiving. (23:21)

This video from ACS features Diane Bunce, Ph.D, professor of Chemistry at Catholic University of America. She demonstrates several holiday activities and experiments, first addressing the procedures for each activity and then discussing the chemistry... concept behind it. The activities include: snow globes - viscosity and density, bounding snow balls - polymers and cross-linking, and holiday cards - polar and non-polar reactions. These "holiday" activities could easily be adapted to other times of the year. Although the activities seem appropriate for elementary level, the explanations given by Dr. Bunce are certainly for upper level chemistry classes. Run time 07:37.
