Developing a Cooking Chemistry Elective

To squash any misconceptions, I would like to say first and foremost I am not a great cook. My husband graciously does most of the cooking in our house. However, as a chemist, I am fascinated by the complex reactions involved in everyday life. Pair this curiosity with the requirement to teach an elective, and the Chemistry of Cooking elective was born.

Hydrate Labs, Microscale Chemistry and Cage Fighting....

Bottle cap set up for hydrates

For years my students would heat the hydrates in glassware, burn themselves, break the glassware and splatter salts and thus their data, all over the lab bench. A few years ago Bob Worley came up with a great microscale technique. Essentially, it takes a used bottle cap without the plastic and this is used as the dish. Next, there is about a three inch machine screw that goes through a drilled hole in the cap. A nut is placed on the screw to hold everything in place and cheap pliers are used to hold the entire assembly over the flame.

The Hindenburg

Teaching the Hindenburg disaster in the chemistry classroom.

I have always been intrigued by the story of the Hindenburg, the iconic airship that caught fire on May 6, 1937. The accident killed 35 of the 100 passengers and crewmembers on board. As a chemistry teacher, I discuss this from a chemical standpoint and the fact that the airship was filled with hydrogen, a flammable gas, rather than helium, a non-flammable gas, as today’s modern airships are.

Quantum Chemistry, Videos and Safety

Student Safety Posters

 I have to be honest. I am not big on showing videos that take up a whole class period. Most videos I try to make or get off of You Tube and usually I can asign them for homework. I never want them to be more than ten minutes long.
