Congratulations to the outright winner - Intel. For the tiny cost of $4million, Intel has hoovered up the greatest ideas of 7 million of the brightest students across the planet. Of course Intel will propose the naming of one of the billions of asteroids (which they don't own yet) after you. Thanks for that.
you should find an affiliated regional fair first and register for it. search it up through the Official website. (plus, just motivation+smartness+hardwork makes it.
Sorry for super late reply but some schools host it, or you can join online I believe. I am doing it through my school, and I have friends who go to other schools that are working with my school to enter. So just find a school in your area that has a science fair program. Just a heads up though, it a hell of a lot of work, and very stressful, it’s my first year and I have never done something this stressful and i have not even gone to the actual fair yet. But in the end it’s worth it if you choose a topic you are passionate about.
