When you decorate the doors of a chemistry classroom in a Christian school at Christmas, here's what you get. The students in my wife's class chose these designs and decorated the doors of their two classrooms. I'm not sure what coffee has to do with anything really, but the Chemistree seems to appropriately blend the themes of the subject, the holiday, and some core values.
These will be up for just a few more days as that end-of-year winter break is upon us. Hopefully, everyone will finish strong as the first half of the school year comes to an end.
