I was (gasp) observed today

Every teacher goes through it and every teacher hates it. It is The Observation. I was feeling a bit nervous because I just found out yesterday he was coming in and I had already known at that point that I had no clue on the subject matter facing me today. I was to teach about how meteorites caused extinction of species. I was never taught this, I didn't have to teach this last year, and I have no materials on it. So I spent all of last night taking information from about ten websites and I created a power-point and notes for the students. I knew going in that the principal evaluating me is not a science guy, but more of a music guy. I prayed that this would be something he didn't know about either and would just take what I gave him and not expect some great insight that I must be missing. He came in and the students asked great questions. I am so glad that I threw in a Christian viewpoint and an evolutionary viewpoint because I realized afterwards that this guy is not a Christian. He even asked me at what time humans evolved. He was great in adding his own personal touch. He learned in my class today that Iridium is a rare element caused by extraterrestrial material. He had been in a jazz club in Chicago named Iridium. He now understands why it was named that way. But overall, he thought the conversation was good- THANK YOU 3rd Period!!!- and he told the head principal about it. I am anxious to see what he wrote down on the evaluation.

BTW, don't get me wrong, principals walk in all the time to check out what I am doing, but an official observation is nerve-wracking.
