Bacteria!

I believe that we are done growing the bacteria for the 4th grade science project. The most interesting bacteria came from under Sydney's finger nails. Most of it was, as best as I can describe it, stringy and swirly.



The bacteria from her nose was most interesting because it has many different stuff growing. I have no idea what in the world it is. The experiment is only to find out what bacteria grows the fastest.

We took a sample from behind her ears. It was slow growing and looks a lot like the sample Melia took from her hands. I ended this experiment at 10 days because I saw what looked like mold growing on the dishes and I didn't want that to get in the way of her experiment. (If I'm wrong here please let me know)
The mouth sample is what surprised me the most. I expected to see a lot of bacteria growing on here, but it's relatively good. I thought that it would be cool to get a sample from a horse mouth, a dog mouth, maybe even a pig mouth, but Sydney wasn't on board with that. (It is her experiment after all!)

Sydney took a sample from between her toes and we were not disappointed.
It grew real fast and then not much happened, with the other dishes not much happened and then they turned colors. That's bacteria for ya!


So her hypothesis was correct, foot bacteria grows the fastest. I would have liked to find out what kind of bacteria we were growing but that takes a lot more testing and she's only doing a 4th grade experiment. Now we just need to graph the results. I think that I'll let the dishes be and look at them later and see how nasty they turn out. Fun, fun!
