In Years 1 and 2 we have been looking at life cycles and our healthy bodies. This week we examined exercise - which exercises would raise our heart rate? We discovered a range of exercises that would definitely raise our heart rate but our clever scientists identified that many exercises, if done slowly, would not raise the heart rate. We discovered that the reason our heart rate rises is to pump more oxygen filled blood to our muscles to help them do the work. A lesson to exercise our bodies and brains!
