Children learning the human circulatory system

Children learning the human circulatory system In Science, we have been learning about the human circulatory system. Last week, we looked at the structure of the heart and its function, then put this to the test this week by measuring how our heart rate increased as we exercised, as the muscles require oxygen at a higher, faster rate.
