What we did in class week 10/16/09

This week we started to test the samples that the school gave us to try to figure out what was causing all of the sicknesses. First my partner and I made all of our objectives for this week to get done. Our objectives were get all of the microscope tests done, write down and get checked for all of the procedures that we wanted to do. And finally actually do the experiments. Our experiments were test the pots and pans from Cheep Chicken Hut and the Chicken also from Cheep Chicken Hut for bacteria by using a petri dish. Our other experiment was looking at the pond water sample under the microscope. and after we finished our experiments we found some pretty interesting results.

In our pond water experiment we found that there was a living organism in the water. We saw it eating plant matter and move around. after doing some research we found out that the organism could possibly be a freshwater crustacea. We still have to do a little more research on it to see if it could be potentially harmful to humans. In our petri dish experiment we closely monitored the progress of the growing bacteria colonies and after a couple of days for both the pots and the chicken had a ton of bacteria on them. I know that chicken has bacteria on it that is harmless to humans so I'm not sure if the bacteria my partner and I found are good or bad bacteria. For the pots there was also a lot of bacteria. I was not surprised by that because it was my hypothesis that is that the pots are where the people got sick from. So, so far we got pretty far in our experiments, with a little more research we will be almost done with our experimenting.
