They're also gearing up for mid-term exams, which will begin the week after next. So they're constantly asking "Will this be included in the mid-term?"
My second-year students are currently doing a chapter on beetles, and it talks about large beetles found in Colombia. For the first half of the students, I just said that Colombia was a country in South America on the Equator and left it at that. For the second batch of students--since there is a girl in the class whose family came from South America--I tried drawing a rough map on the board and circling Colombia.
I erased it soon afterward. Let's face it, my board-drawing skills are stick-figure level. And the snickers from several of the girls made me think that, no, I was not alone in imagining that my version of South America looked like male anatomy. @_@
