Mr. Finley went around and checked that we did our homework; the places where we would find less and more bacteria and the video we took notes on. Louis Pasteur's one container grew bacteria because the broth was food for the bacteria. The bacteria grows once it starts feeding on the broth. The other one didn;t get any growth because the swan neck was not broke. Things were not just growing out of no where something had to go into it for it to be able to grow.
Areas with more contact have a more better chance of having a lot of bacteria on it.
Places in school with a lot of bacteria would include: door handle, and finger scan
Places in school with not a lot of bacteria would include: door handle when you come OUT of the bathroom.
A petridish is a round dish you can test things in.
An agar is a stubtance bacteria grows on.
We labled our petridish and put it into 4 differnt sections. We got a swab that is sterilized which means it is CLEAN.
Then we tested!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
