why not use your library for science articles? i did a bio term paper last year for AP bio and i used the Welseyan Library (my mom works there) and found everything i need and them some. you may not find something having to do with the home aquarium, but you should be able to find something on the nitrogen cycle, and the tests were probably done in a home aquarium.... no?
anyways, i see you are in chicago, what college are you goign to? My girlfriend goes to school out there and i am applying.
i'm actualy going out on wednesday (valentines day:clap: )
