Small (liberal arts?) schools with good science?

i'm a high school junior trying to make my college applications list. i'm not a genius but i get quite good grades and do extracurriculars and sports and things. i've visited several colleges so far and think i definitely want a small or medium sized school, NOT a big research institution. i'm from a small town and very much like the friendly, familiar community feeling of a small school. also, i'm kind of a nerd and i like the smart, quirky, driven people at prestigious liberal arts colleges. however, some of the small schools i've looked at (macalester, bates, middlebury, williams) don't have very good science programs or science research. i am almost positive i want to study some kind of science, probably biology or medicine rather than chemistry or physics. any suggestions for small or medium (try to keep it under 15,000) sized schools with good science? liberal arts would be nice but is not an absolute requisite. schools i've already found that seem to fit these criteria include wesleyan (noted for good science), reed (good research, i've heard), rice (a bit more math-focused than i'm looking for but still nice) and case western (not liberal arts at all). i'm not hugely picky about location but i'm not too enthusiastic about the deep south. thanks for any suggestions!
