To add onto what everyone else said
, you should also search the web for veterinary societies. Just like SME and all the other engineering ones, many professions have national societies that offer scholarships to students that want to go into the field someday. This is also a helpful way to find people who may be hiring in your area.
Also, ask your family about their experiences. Being the relative of someone with military experience, in a society, or just worked for a certain company may open you to scholarships you didn't even know existed.
Building on what Amanda said, there's also ways of selling skills that you acquired through FIRST that aren't science and tech based. Maybe you did some PR, and thus you would have presentation skills and writing experience. Maybe you did some strategy, it would show that you know how to think analytically and come up with solutions that other people would not usually find. Maybe you helped your team's cheering section...thus, you have motivation and leadership skills! With colleges, its all about the spin you put on it
Good luck!
