Who Dunnit?

Thank you Shark parents who contributed to the CSI experience at the auction.  The Sharks LOVED it! Mrs. Olson and her assistant Amanda were very impressed with their reasoning skills, as they studied the crime scene to determine what happened.  After an initial investigation, the Sharks had to examine the hair, finger and footprints left behind at the crime. We practiced these skills earlier in the week so they would be prepared. One student described fingerprints like a tire tread, and that's why it leaves marks. Others observed that one piece of hair has several layers, like a pencil.

The Crime: One student was painting a picture of flowers. They left for recess and when they returned, the paint and vase of flowers were spilt, and the picture destroyed on the ground. Three students were the suspects.  Now, on to collect evidence...
