Reflections on a (Virtual) Guest Speaker Visit to my Chemistry Class

I've mentioned previously that my current grade 10 class is reading "The Case of the Frozen Addicts" together. As my students starting writing their blogs to respond to the reading, I saw quite a few questions that I couldn't answer. But I didn't want to leave the questions there with no response, so I went to Twitter to find scientists to join my class as a guest speaker.
