The Teacher Page includes all of the notes I need to set up, run, and clean up the particular experiment. I record from whom I obtained the lab. I list the location of chemicals in the stockroom. I've added what does and does not work, so that I don't have to remember it from year to year. I have notes of things to try in the future. The most important part, however, is the giant spreadsheet to calculate amounts of chemicals needed to make multiple volumes of solutions. This saves so much time and repeated effort!
