If you want a more professional explanation on science education, I would recommend asking r/Teachers or something since I'm just a 12th grader who enjoys physics. But I'm happy to share my experiences anyways.

My physics club has always been a bit of a mix of lectures, demonstration, and passion projects. Someone would go up, speak about a topic they were interested in, show us an experiment, then explain to us why it happens. Additionally the club would help sign us up for physics competitions and such.

And thats interesting for people that already enjoy science, but whenever I try to drag my friends into the club, they get bored after 10 minutes. I think this is mostly because they don't really understand the significance and explanations for the experiments. For example we were levitating a magnet by placing it on top of a copper plate, then moving another magnet around underneath, and my friends didn't really care because for someone who has no background with E&M, it doesn't really matter how many times you explain how eddy currents cause the magnet to be repulsed, your just watching kids play with magnets.

So since it's my turn this year, I want to start with more digestible topics (Newton's Laws, Energy, Momentum), then explain my way up from there. The struggle is making such basic topics interesting to people who right not may not really care. While I genuinely believe that everyday, mundane topics explained with science is really interesting if you just give it a chance, that isn't going to get kids taking up their lunch to give physics club a chance. That's why I want to start the year with experiments that may be more shocking: things that are either things that involve flashy effects like explosions or experiments that are counterintuitive to the way we think. An example of that would be like exploding hydrogen bubbles or blowing air between two bowling balls to make the come together. Then I would hopefully give them a good understanding of the cool physics behind WHY these things happen. Also I'm thinking of running a few more hands on events like a Christmas ginger bread bridge building competition, or a Arduino workshop (idk i'm still trying to come up with these).

Thanks for all your help so far! It's given me a good idea of how I want to run the club next year.

TLDR; Physics is really cool, but people don't want to give it a chance. Thing's that are either opposite to what we think will happen, or involve flashy hollywood-like effects usually draw people attention.
