Does exercise effect our heart rate?

After finding out about the different chambers of the heart and the functions of arteries, veins and capillaries- we decided to put our investigative skills to use. We started by finding our pulses, which is not as easy as it looks! Then, we moved onto trying different exercises, which were low, medium and high impact, our favourite was the floss and burpees.  We took our pulse for 15 seconds and then used our math skills to multiply this by 4 to find out the beats per minute.
