This post is comprised of questions (Qs) that challenge students to apply the knowledge acquired in their chemistry education to COVID-19. The questions encourage students to think across scientific disciplines, to think 'outside the box', and/or 'connect the dots'. Understanding how SARS-CoV-2 works inside the human body is every bit about chemistry as it is about biology as it is about physiology.

The practice and the promulgation of science, its ideas, and knowledge acquired about how the biotic and abiotic world works depend significantly on what words are chosen to communicate scientific ideas, methods, thought, and information. This blog post looks at how a recently published NY Times article on the growing evidence that the SARS-CoV-2 virus can be transmitted via the air can be used in the classroom to promote discussion and challenge students to think about the distinction between data and evidence. If applicable, it could be expanded to also include the difference between opinion and information, if desired.
