My 6th grade science project concerns testing 3 stain removers to see which one works best on stained carpet. My teacher accepted the topic but now she says that it is not a good one because the conclusion cannot be scientifically reached. She says that I cannot have a number of people just look at the carpet samples to decide which cleaners work best. My grandma and I looked on the iinternet and found that there is something called a colorimeter. Where could I find one that I might be able to use. I don't have much money. I have called laboratories from the yellowpages and school science departments. Can I use something else? Or where else should I Look? Thank you, Emily
