[Reflection: Plan an efficient way of pouring all the various substances for the students. I did not plan enough in advance, wasted a few minutes of class time pouring liquids for the students, and kicked myself for it later. I had the students stay seated and pass the substances from table to table. The final class, I had the students rotate the classroom for set amounts of time at each station. This worked the best.)
