the 2 chemistry professors are preparing experiments for the next day's lab. the leader of the chemistry department had given theme few guidelines about what they should include into their experiments in order to test the knowledge of their students. they are nervous because they are both first year professors and although they know full well what will come out of each experiment, they want to make sure they understand the experiments completely in order to impress their students.  they are hoping that the next day, when their class arrives, they will be excited to explore the world of chemistry and to see how it can relate to the real world.
