Part 1
Fill in the number of heartbeats per minute which you calculated from the Activity lesson page.
Heart rate while dancing: 72 beats per minute
Heart rate while studying: 64 beats per minute
Heart rate while riding a bike: 80 beats per minute

Compare these heart rates and explain why they are different.
Your friend stopped jogging to take a 15 second quick count and counted 40 beats. Show or explain how she would find her beats per minute.

Answer 1

They are different because you will be going at a different ‘speed’ or you may be more active , less stressed?

Answer 2

The heart rate is different while dancing, studying and riding a bike because the amount of blood needed for each activity is different. Blood pumps as fast as it as needed by the cells, which is why riding a bike has fast heart rate while studying has a regular heart rate.
