I'm a teen! I'm 18 to be exact (its a good age
).
My experience (with my friends and others I've met at least) is that none of them have ever been given the opportunity to get involved in anything astronomy related, but they are still interested in giving it a go. For me during high-school (I'm a uni student now), we didn't have astronomy classes and in physics we spent maybe 1 or 2 weeks learning Astrophysics 101 in our whole 2 year course - nothing practical. I think this is a shame because most of the time whenever I'm talking about my hobby to other teens (at parties, outings etc) most are quite interested. I get plenty of "You'll have to show me stuff through your telescope sometime!" I think more telescopes in schools would be a good thing because (from my experiences at least) there are a fair number of teens who wouldn't mind a look through a scope - even if it's only one time just to see what it looks like. We'd probably get more teens around here too!
