Proper technique for swabbing the agar.
Students swab a sink drain in Room 170
Students collected samples around the school in an effort to answer the question, “What location at the school has the most bacteria?” They followed the procedure established by the class yesterday. Petri dishes were labeled and placed in an incubator at 37 degrees Celsius. We will check them tomorrow. Students began to write a letter to Dr. Greenholt that explains the reasoning behind the investigation and the results (when they have some).
This experiment is exciting. To actually understand where germs live and how they reproduce and form can help when trying to keep a specific area clean.
Interesting experiment. I’m curious to know where the students found the highest concentration of bacteria and what will be done about it.
Reading the short summary makes the experiment the students did seem very interesting. This seems like a great idea because you can never know where your gonna find a lot of bacteria. This was also a good idea because there are tons of students that go in and out of somewhere and if wouldn’t be a good if any of them got for example meningitis like my youngest daughter had back 5 years ago. It can be a very scary thing. Students should make sure they wash their hands good and clean up after themselves.
I think this is a very hands on way for the students to contribute to their experiments. We never used this type of technology during my years. This is an interesting and careful way for the students to understand bacterias and other science related information. I enjoy the how this class works. – Stephanie D.’s mother
This is so cool that you are doing this! I will want to know the results when you get them! I sure hope it’s not in the kitchen that you find the most bacteria!
