5TH GRADE

Science Concept: Effects of exercise on heart beat rate

In children the heart beats about 100 to 120 times a minute. In grown people it beats about 70 to 90 times a minute. When we exercise the heart beats hard and fast. The cells of our muscles need extra food and oxygen when we exercise. So the heart must beat faster and work harder to take more blood to the muscles.
