In science we are learning about the circulatory system and how the heart works as a double pump to enable blood to be oxygenated and  then the oxygenated blood is pumped around the body before returning to the heart and then being pumped to the lungs to be oxygenated again. This is a complicated and abstract concept to understand so to make it easier we act the various processes. Some children are various body parts while others are the blood, the children who are blood have to carry blue or red cards depending upon which part of the cycle they are in. The children get to complete the cycle a number of times before swapping roles. This will enable them to picture the concept more clearly and understand what is happening. Here are some pictures to show you the lesson in action!
