What is something technology-related that I could teach 12 year olds at a camp?

I am a candidate to be a camp counselor for 12-year-olds at our school district sponsored camp this may. I have to do an interview where I will be asked questions and I will need to convince them that I should be a camp counselor. I myself am very technologically savvy and was thinking of using that to my advantage. While it doesn't seem like an outdoors camp would need technology, I need to convince the leaders that I could be an asset to them. I was planning of running a blog where parents and family members of the 12-year-olds could read and see photos of what is happening at camp. I'm also considering filming important events during the camp. What I'm stuck on is how I can teach the kids how to do something or how to make something that is technology-based. I was thinking about something dealing with photography, but I don't have that many cameras at my disposal. Does anybody have any other ideas on what I could do?
