This week in class I was absent for Monday, Tuesday and Wednesday but I was there on Thursday. On Thursday my partner and I did some more research about what bacteria could have been in the chicken. From doing some research we found that salmonella symptoms start to take effect after about a day or two. When most of the kids were sick it happened one or two days after a band class or competition where they went to Cheep Chicken hut.
Other kids in the class have done a gram test on the bacteria they found. My partner and I still have to do it and will hopefully do it on Monday.

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.

what we did in class 10/8/09
So this week in Mr. Finley's class we furtherr dicussed whether a bacteria is living or non-living. We finally came to a conclusion that it is not living. While bacteris may have some things that make it look living about it, it does not have all of the characteristics to be living. The other things it needs to be living iit needs to have a host (a human ) to support it. So now we know that bacteria is something that is non-living.
What we also did in class this past week was get samples of the some of the things that we think may have caused all of the kids being sick for school. We got pond water, pots from the resteraunt, chicken, and blood samples. My partner and I decided on what kind of experiments we would like to do. For the things from the kitchen we decided that we would use a petri dish that would test to see if there was any bacteria on the items. For the pond water we will use a microscope to see if there is anything that could potentially make us sick in it. we will do the same thing with the chicken from the resteraunt. Finally Mr. Finley will do the experimant on the blood samples. We will do most of the testing next week.

what we did in class 10/3/09
This week in class we did a cool experiment. We took petri dished that Mr Finley made for us ( thanks!) and took samples of what our group would have bacteria and what wouldn't have bacteria. My group will check the progresss of it every day in class to see if our hypothesis we made were correct. The first time we will check the petri dishes will be on Monday, three dyas after we took the samples.
The experiment was in class to go into a bathroom(I went in the girls bathroom) and take swabs of what we thought would have bacteria. My group took a swab of the door lock because everyone touches it and the janitors may not have time to clean it. we also took a swab of what we thught was clean, the sink drain. We thought this would be clean since all of the water and soap go down it and that wold wash out most of the germs(hopefully!). I can't wait until monday to see the progress of the petri dishes.
