College Essays

Hello,
There is this one college essay that talks about a certain topic/inquiry that you would like to research and/or look into. All I ever do are science related activities (along with some cultural activities and volunteer work).
I am afraid that if I talk about a scientific inquiry, I would be posed as being too one-dimensional.
How do I pose these types of essays?

So come up with something non- STEM that you would like to learn about.
