In science, we have been learning about the circulatory system. First, we looked at the heart and learnt about how it worked. We found out that it has four chambers and is a double pump; it pumps blood to the lungs to be oxygenated. The oxygenated blood then returns to the heart to be pumped around the rest of the body.
Next, we learnt about double circulation. We modelled this outside on the playground. Some of us acted as the heart, some oxygenated the blood in the lungs and others took the oxygen from the blood for the rest of the body. Everyone else was the blood itself! The blood had to travel round the body and through the heart twice – taking great care to enter through the atriums and leave through the ventricles! After this, we had such a good understanding that we were confident to draw and label diagrams of the body’s circulatory system.
