I just got back from spending a few hours at school, setting up some stuff in my room, when I discovered that the air-conditioning is not functioning in my room. Each room in our school has its own individual unit, connected to the same system. So, the AC is working in the rest of the building, but my room. I'm up on the third floor, and you all know about how heat rises. Needless to say, it's very, very hot in my classroom right now, and there are only three windows. I told the powers that be about the problem, but I'm worried it won't be fixed before school starts. Have any of you had to deal with a terribly hot classroom? What did you do? I'm thinking of allowing water bottles, until the AC is fixed, only because I don't want a parade of students going to the water fountain all day. Any thoughts?
