Today in class Mr.Finley started off the period by talking about having the class observe their bacteria for the very last day. This is day seven, my group over the past week has had a-lot of bacteria growth. The most bacteria came from the middle school bathroom toilet. We also tested my locker which is 120A. We also tested the middle school bathrooms urinal. The last thing we tested the middle school bathroom mirror. The most bacteria growth came from the middle school bathroom toilet. there was a-lot of bacteria from others but the toilet had the most. Also we have mold covering nearly the entire peachery dish. The least amount of mold came from my locker corner. The percents of the mold growth is huge since the last time we checked out peachery dish. We had 52% of my locker covered in mold. There was 95% of the bathroom mirror covered. Then the toilet had 97% of bacteria covering it. Then finally we had the urinal which we found out had 80% covering it. I notice though that the locker corner had no bacteria at all. I think this is because the locker corner didn't come in contact with anything. So I came up with a hypothesis. It was that untouched areas will have less bacteria growth then contact areas. Like your foot would have less bacteria than your hand. Now we are going to observe bacteria that is macroscopic. Macroscopic is bacteria that is larger than microscopic bacteria but you still need a microscope to see it. But we are going to observe them in colonies (large numbers). And we are going to use a stereoscope to observe the colonies. A stereoscope is something you use to magnify things. Basically its something that you can see as a human but it helps you get a more detailed picture of the object like a spider. When I looked at the bacteria the mold was hairy. The bacteria had a bubble wrap feature to it. And that's how my day in science went. I have posted a picture though to show you the difference between bacteria and mold.
