In Science, we have been exploring our big question, “Why is the heart the most important pump we own?” Children have been learning about the main parts of the circulatory system, what they do, and how we can keep them healthy. We have labelled the different parts of the heart and investigated how our heart rate changes in different scenarios, such as during exercise and rest. Through research and discussion, pupils have also learnt why keeping our heart healthy is so important and how our everyday choices can have a positive impact on our bodies.
