I'm going to say this from the perspective of someone who was a freshman not all too many years back. Entering high school, and being still under some delusions about what high school is really all about, there's tremendous pressure, especially if you're generally motivated, to distinguish yourself from your peers. Nowadays, as early as middle school the idea of working your ass off in college and figuring out what you want to do with your life in sixth grade is touted around as the correct way to go, and I know personally that I felt a lot of pressure to do something "adult" in order to show what I'd accomplished.
So, as early as middle school, I started writing a book. I poured hundreds of hours into it, and most of one entire summer. I worked on it on and off throughout middle and high school, I consulted adults, I edited it countless times, I attended seminars on writing and publishing and self-publishing and editing and fiction and everything I could possibly do to become a star author at the age of whatever. I envisioned myself writing my dissertation for my college application essay (news flash, most essays are like three hundred words) about how I'd accomplished such a feat at such a tender age, and I thought it would show my continuing drive and motivation throughout my life.
I'll be applying to college later this year. I very much doubt that I'll write about the book, and if I do, it won't be anything like what I thought it would sound like. In just the last year, much more important things have happened to me. I started coming out, I got a job, I went through experiences that made everything in my life before seem trivial. To this day, I've never published that book. It wouldn't take more than a couple of hours to put together a quick cover and self-publish it somewhere and forget about it, but I haven't done so.
I'm not trying to discourage you from writing your paper, or doing research. I think it's great that you're challenging yourself academically, but I don't want you to be misled by how you feel now. However intelligent and smart you may be now, you will be infinitely smarter in a couple years. The work that you'll be able to put out when you have a couple more years of experience under your belt will be incredible compared to any research paper you can write now.
If you want to write this research paper, you should absolutely do it. However, before you start, you need to look within yourself and ask yourself whether or not you're writing it because you're genuinely interested in the topic and you genuinely want to spend hundreds of hours researching it and writing it up even with the knowledge that you might never use it for applying to college. On the other hand, if you're writing it merely because you feel like it's expected to do something amazing at a young age to get into one of these schools (it's not, by the way), I would absolutely refrain from doing it.
Please note that I'm not saying you're already highly accomplished where you are now in your life. I'm sure you're plenty smart, and I'm sure your grasp on language and the sciences is adequate enough to write a coherent research paper. However, I have yet to meet a single person in high school who hasn't grown as a person and become smarter and more honest with themselves during the course of high school.
tl;dr if you really want to do it, do it. if you feel obligated or compelled by societal standards for high-acheiving students that may or may not exist, don't.
