I would say that the experiment is on the easier side for a junior, but that should not stop you from doing the project if that is what you are truly interested in. If you want to do a more complicated project dealing with bacterial disinfectants, I would suggest this project, as it deals with concepts similar to your earlier proposals: http://www.sciencebuddies.org/mentoring ... ?from=Home

If you want to stick with your bread mold idea, try these 2 sites and see if you get any help from them:
http://www.madsci.org/FAQs/micro/molds.html
http://mps.k12.vt.us/msms/grade6/6grade.html

And if you continue with your current idea, think of using an entire range of light, with complete darkness at 1 end of the spectrum and full light at the other end. Think of the spectrum as an asymptote; the different shades of light will constantly approach darkness and light until they get there [unlike an asymptote they will reach the ends]. You could also do some research on the effects of different types of light on bacteria to see if you want a special type of light such as a UV or blacklight.
