Chemical Illustrations of Flattening the Curve

Dean Campbell | Sun, 03/22/2020 - 18:24

With the current global COVID-19 pandemic, there has been much discussion of “flattening the curve” by social distancing. These ideas can be demonstrated chemically, for example, by the iron-catalyzed decomposition of hydrogen peroxide to produce an oxygen gas foam. Decreased hydrogen peroxide concentrations, representing decreased human population concentrations from social distancing, produce oxygen gas foam, representing cases of illness, at a slower rate. A similar demonstration can be achieved using the popular Diet Coke and Mentos experiment. These simple experiments are best used as stand-alone demonstrations.

Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium. 

Assessing the Assessors

Francisco Villa | Tue, 01/21/2020 - 15:10

A lot of time is spent assessing students but how much time is spent assessing ourselves and our peers? Some faculty take departmental evaluations seriously and professionally while others prefer not to for a variety of reasons. What happens when a faculty member introduces evaluation guidelines into a department that had none previously? Read and find out.
