The Primary students have started a long unit on learning how the human body works. This past week included the study of respiration and circulation. After having studied nutrition and digestion in the previous unit, we knew that the body needs nutrients. We learned that oxygen has needed nutrients as well as food. The lungs and heart work together to bring oxygen to the blood.
Works on the shelf helped us explore respiration and circulation including puzzles, a stethescope, models and a science experiment using balloons to see how our diaphragm pulls air into the lungs.
