My favorite biology class was 7.06 (Cell Biology), with Professors Cheeseman and Orr-Weaver. Prof Cheeseman broke our recitation into four Hogwarts Houses, and held an inter-recitation House Cup. (Our team was Hufflepuff, which I found quite fitting.) He’d show us slides and we’d have to work together to figure out what was being shown in order to earn House points. It was a great learning experience and a super creative way to get us all engaged in the subject matter.
