It's that time again! The Fourth Grade Science Fair. This year the projects were well conceived and presented. The young man on the bottom row actually made a potato gun out of PVC pipe. The skull next to him was determined to be that of a raccoon based on deductive reasoning using size and shape of teeth and head. I love the question posed at the top right. Unfortunately i didn't have time to find out. I may have to do my own experimentation.
