Double Les's thoughts, we do a workshop for teens every summer.It is a week long , 4 hours a day session. So, Keep it simple. They will ask what they need to know and will get to where you wanted to go. That is not to say that you don't cover the basics but give them just enough understanding about how to use the camera and send them out to make pictures. Then all that "nuts and bolts" will begin to make more sense.
One thing that was great fun (and i had serious questions about) was to do "photo grams". This was a lead in to printing negatives. It gives them the opportunity to handle the equipment, use the process etc. I was blown away with their results. I was also surprised that they would enjoy something so simple. Some wanted to know what would happen if they put their "chemical hands" on the paper; so my response was go find out. THey began to do chemical painting and it was a wonder.
Another really great experience was to mount, frame and have a mini show of their work at the end of the week. While we mounted, spotted, framed, etc, the gallery director hung each students work along with a proper name card in the gallery area. We had ask the parents to come for cookies and punch at the end of the day and surprised them with a photo exhibit. It was all very professional and folks loved it.
One parent even comment "my gosh these photos have contrast". However, more important every one had a great time and wanted to go out and take more pictures. they all were so proud, even if they didn't act like it (remember these are teenagers); however, the parents couldn't believe their children produced these images.
How many really understood fstops and shutters speeds? Who knows? How many really grasped the fine points to printing. Probably none, but they had fun, got excited about taking and making pictures. Wanted to continue having that experience.
Plant the seed; who knows what will happen! The reality is you may never know
