Bacteria Experiment

The class looks at slides of different shapes & colors of bacteria.

Our petri dishes with some growth!
This past week, our class was introduced to the Scientific Method. 
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!

  1. Very cool and interesting! Tanner loved it and told us all about this science experiment!

    Im alittle embarrassed to say we havnt played the school websites games(links) until now! They are so great and educational! We will have to show our 3 year old some of it. We go on other educational websites but not through the school...really neat! Tanner enjoys doing it at school and now at home. He loves the comic strips,also making up characters and reading on it. Thanks for all that you do for him!
