Science Buddies: "Ask an Expert"

I need 5 sources of background information about my chosen test subject for the science fair. My problem is that I only have one and not 5 and I don't know where I can find good sources online for this. So, if you have any ideas or know anywhere I could find sources for my project that would help a lot. Thanks! P.S., My project is which surface has the most bacteria?

Did you try searching in ScienceBuddies? There have been many questions on this topic over the years and you can probably find some links to sources of information in some of the posts. Otherwise try Google Scholar for your search. You should find lots of hits on this subject.

Good luck!
