Last year I won the Middle School science fair with your project "Going Green As You Clean". This year I need to expand on this same project. My teacher suggested using medaka fish instead of worm, but I can't figure out a practical way to design this experiment since medaka fish need a filtration system, heater and lights. Any suggestion? I also considered using water fleas which seems to be easier. Which would be a better experiment for high school, in your opinion?

- Project Question: We tested antimicrobial soaps vs plain soap vs hand sanitizer using the Kirby Bauer method. We were surprised that there was no zone of inhibition around the hand sanitizer. Our product is 62% ethyl alcohol-the same as we use in the hospital.I think it is because the alcohol either evaporated, or because it is only able to kill existing bacteria, not inhibit bacteria from growing. What do you think? We were also surprise that there was a zone around the plain soap. What would acount for that?

Re: Expanding my project
Based on the information you posted, I'm not sure I can answer your question. Could you explain a little more about the project you did last year? How did you use the worms? Presumably you want to do something similar with fish or water fleas this year. If you post more information, I'll help you as best I can.

Re: Expanding my project
Hi,
Expanding on a previous winning project is an excellent strategy. I think this is the project you did last year:
https://www.sciencebuddies.org/science- ... p053.shtml
If you use fish or another vertebrate animal, you will need to get approval for your project before you start. So, working with water fleas that don't require filters or special equipment would help avoid these issues. You could do an excellent project with either fish or water fleas. What were you thinking about doing this year?
