The class looks at slides of different shapes & colors of bacteria. |
Our petri dishes with some growth! |
Mr. Keleher came in and helped the class design and implement a REAL experiment!
The question was "How CLEAN is our classroom?"
We listed our materials and made a hypothesis as to which part of the room we thought to be dirtiest. Mr. Keleher swabbed 5 areas of the classroom (to test the hypothesis).
(doorknob, teacher's table, chalkboard, soap dispenser, pencil)
...and as an important aside, the class wanted to feel the inside of a petri dish...this was the 6th dish...
Ask your child for the results of the experiment! What? Did you think I was going to give it away?
Thank you to Mr. Keleher!
