POGIL, Posting Keys Online, Cheating and Checkpoints

We had just had some snow days and I had the feeling that I was getting behind. In one class we were approaching the topic of orbital diagrams and electron configurations. I was tempted to just say, "Here are the notes." Sometimes there is nothing wrong with that. This time, something was eating at me. Instead I picked a POGIL (link is external) from the "High School Chemistry" (link is external) book that presented the ideas through guided inquiry.
