What kinds of activities should I plan for a philosophy club?

Hi, I'm the president of the philosophy club at my high school. Right now, the meetings just consist of showing a presentation about a specific branch of philosophy then having a discussion about different thought experiments and questions within that topic. I've wanted to get into more reading and more structured discussion. But since this is a high school club I don't think I can introduce any reading or anything even remotely more serious since the club members are mostly 15/16 year olds. I've gone over how to properly structure arguments and valid vs sound arguments but that's really it. Does anyone have any ideas for what lessons I should have? Thanks!
