WHAT's growing WHERE??

It is always fun having a scientist in the family. A few weeks ago, Dave brought home a petri dish to see what was growing in our carpet. It turned out that there is A LOT growing in our carpet. It was disgusting! That got the scientist wheels turning. If there was stuff growing in our carpet, where else was there nasty stuff growing? I will give you four guesses.
Dave came home the next week with petri dishes for each girl. They were each labeled "mouth", "nose", "ear", and "hair". For our family activity that night, we used swabs to collect samples from around each girl's nose, behind their ears, and in their hair. We collected from inside Ciera and Chloe's mouths, but Brooke and Autumn didn't want to do in their mouths, so they did their belly buttons instead.
A week later we looked at the results. Let me just say... Yikes. It turns out that they are regular breeding grounds for bacteria. Sometimes I think it is better not to know... you know, ignorance is bliss and all that. Oh well... all in the name of science.
