My school had a "Holocaust" week when I was in 8th grade. They re-enacted separating out specific kids as "jews" (they were chosen at random not based off anything) and discriminated against them in various ways on the first day to give an idea of what it was like. We had no advanced warning this was going to happen we just came in one morning and all the teachers were in the gym pulling people out of their various groups secret police style and lining them up. I actually got in trouble for giving one of them a piece of candy later in the day. All our classes were put off that week and it was just learning about the holocaust in detail all day for the whole week and they did not pull any punches. I still remember some of the images they showed us to this day. At the end we had to do a presentation on ANOTHER genocide (I got Khemer Rouge) and go into detail on that one. Honestly it was one of the most educational experiences I ever had in school.
