I'm an 18 year old scouts member; which makes me one of the "elders" of the boy scouts. My chief has asked me to prepare an astronomy session to teach to 11-16 year old boy scouts. I'll be joining them on their summer camp in 2 weeks time. So I'm supposed to wake them up in the middle of the night (perfect setting for teaching astronomy i guess) and give them this session. What I need help with is finding a subject which is both academic and entertaining at the same time. I also consider integrating said subject into a "story" (maybe involving Greek Mythology or so) and eventually giving them a game to play at the end of the session. I wondered if the boys would be able to survive the session and even play a game at the end considering it'll be past midnight, my chief assured me that they would be more than excited. To rephrase in the form of questions: What are some interesting topics in astronomy that can be easily understood and probably admired by the boys? Is there a way to make a story out of it and create a game? PS: Anything that can be easily viewed in the night sky is also probably possible since i downloaded the Sky Map app. Answering even one of the question would be lots of help so thanks in advance and sorry for the long post.
