Mrs. Marcy's Germ Experiment

Note from Mrs. Marcy:

We are starting an experiment in my second grade Science classes. We are testing how germs affect bread. We've got one slice of each bread that is fresh and untouched. The others have been passed around the class or rubbed on various classroom items, doorknobs and walls. I'm going to take a picture at the beginning of each week, beginning Jan. 6th

This is Week 1.

 

FINALLY, A SLIGHT CHANGE AT WEEK 4!!

LOTS OF CHANGES AT WEEK 5!
