If you could teach any additional subject to a mixed ages group of middle school students (10-14), what would you teach? Classes are called "seminars" and last either 90 minutes once a week, or 30 minutes 3 times a week. Each class lasts only one week. Students cannot have any homework. Should be high interest, able to do different activities with, and meaningful to students' lives. So far I can think of military and war, or simple psychology.
