Our first STEM project.
We are learning all about germs and how fast they can spread. We have three pieces of bread we are testing for this experiment: the dirty bread, the control, and the clean bread. We had 80 first graders touch the dirty bread. We also put the dirty bread on the classroom/hallway floor and on the bottom of Mrs. Ragland's shoe! The control was taken from the original packaging with a plastic glove, and the clean bread was only touched by Mrs. Ragland after washing her hands. We want to find out which bread will mold first. Check out how the kiddos feel about this Dirty Bread experiment. I think you can tell from their faces. Which bread do you think will mold first?
