Today, we began learning about moving blood. Atticus read three different friends' opinions about how blood gets transported to different parts of an animal's body. He chose which friend he agreed with most and explained why in his science workbook. We performed a lab activity in which we placed a fresh leaf in a cup of water, waited 30 minutes, then observed little CO2 bubbles on the exterior of the leaf. Atticus described and illustrated the phenomenon, then explained why he thought it was happening.
