Photography - Merit Badge that is

Sunday night in a moment of weakness I volunteered to teach the Photography Merit Badge. So tonight I was working with 9 scouts talking about photography. First thing is 12-16 year olds who sit for hour in school and have finished homework are incapable of sitting quietly and listening. So even thought I'm passionate about Scouting and Photography, I'm not so enthused about trying to get scouts to sit still for 45 minutes. With photography I have found the hook, let them criticize my photographs, and than make them explain what is wrong and than I can explain why it's wrong and how to fix it. I just wish I had fewer photos capable of teaching what not to do.
