Hi, everyone. I'm not sure if this is the right forum as this isn't a simple question-and-answer homework assignment, so please excuse me if this isn't in the right place. I posted this in a different forum earlier and I think it got deleted, so apologies for the double posting. I'm a high school senior in an advanced class, and for fourth quarter we are doing independent projects. I chose quantum physics as my area of interest, which I sort of regret now... But I've been researching it all year, so it's too late now. I need to spend a total of 80 hours on this project. It doesn't need to be one thing; it can be multiple projects. I had originally intended to build a particle accelerator, but have had to abandon it because I cannot find a way to generate a vacuum light enough. Now I'm stuck on ideas. I'm currently doing an experiment with an electron tube to determine the mass of an electron, but that won't take 80 hours and the rest of my project needs to be a bit more original than that. Ideally it would be something with an independent variable that I could adjust and do multiple trials. I could get away with something that doesn't directly relate to quantum physics per se, so long as it could somehow be included in that umbrella. I've thought about diffraction experiments, but I can't think of anything other than a simple double-slit experiment. Please, does anyone have any ideas? I would be eternally grateful.
