Stamp of the Week #2

Germany issued a pair of stamps that honor two fundamentally huge accomplishments in science in 1994. The Quantum Theory and Ohm’s Law. They were really well designed stamps and very accurate in their science.

Chemistry on Stamps #1

Michael Morgan is the president of the Chemistry and Physics on Stamps Study Unit. He has collected stamps and shared his interest with others for almost 30 years. 

Teaching in the Time of COVID-19

No one really knows how to immediately transform an in person class to a distance learning environment. We struggle to provide an equitable education, whatever that looks like, for all our students and make accommodations for differences in learning abilities, home lives, internet access, in addition to mental and physical health.

Chemical Illustrations of Flattening the Curve

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.

Critical Thinking vs. Critical Pedagogy

I recently participated in a conference known as the Digital Pedagogy Lab as a fellow, which required leading a workshop (or an equivalent). I chose to structure my workshop around the ideas of critical pedagogy and STEM, and particularly how we use these ideas in a practical way in the classroom (both F2F (face-to-face) and DL (distance learning)). This blog will be one of a two-part series on these topics.
