Science Fair


Last week Isac participated in the Science Fair at school.  For his project we took swabs of the toilet, trash can, and a few other places around the house and grew bacteria samples from them.  We then tested which household cleaners would kill the germs the best.  Bleach, Lysol, and antibacterial hand soap all worked but regular dish soap did not.  We all had fun and are proud of Isac (and Ryan) for the work he did.  He didn't move on to the District Fair but our friend  Katrina K. did. Her project tested which toilet paper is most absorbent  with Kroger brand suprisingly winning.  I thought we would
share some pictures of the project. These lovely germ samples came from our Toilet and Trash Can...

Good job Isac! That is a pretty gross experiment to do. I can't believe that dish soap doesnt kill bacteria, that is a little scary! How did the Lysol do?
