How To Come up with a Science Fair Idea
I think the hardest part of coming up with a compelling science fair idea is creating something that means a lot to you, is complex enough to perform highly in a competition, is doable, and is relevant to society. From my experience, the best way to do this is to FIRST come up with a problem. This could literally be anything, even if you think it isn't a problem which your interests could easily cater to. Just start brainstorming, from the world's biggest problems to slight problems which could have major repercussions. Once you have your problem, do research into the problem, clicking on official papers online. Then, hop from link to link like a "wikipedia speed run", specifically searching for things that your interests could provide remediation for. By the end of this, you should have an extremely narrow focus and a very, VERY specific part of the problem that you are fighting against. Finally, research into current possible solutions that have been promoted against the specific problem, and figure out which one of them best ties back to your interests. For example, if you like math and the problem that you have relates to energy conservation, then see if you can model some aspect of the problem using math or frame your solutions mathematically. From here, you can come up with your idea and experiment! Let me know if you guys have any other ideas surrounding coming up with an idea. Hope this helps!
