Bubbly BBs and Vaccinated Mentos: Chemical Illustrations to Promote Public Health Measures

The authors revisit "flattening the curve" demonstrations published during 2020 to see how they could represent the impact of vaccinations on the COVID 19 battlefront. These demonstrations do not demonstrate the mechanisms of vaccines themselves, but are rather analogies to their potential effect on a population. In these analogies, gas production still represents illness, but this time people are represented by objects added to the solutions which either enable gas production (unvaccinated individuals) or do not enable gas production (vaccinated individuals). These simple experiments are best used as stand-alone demonstrations, and links to videos are included in this writeup.

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.
