A Beating Heart Lesson Plan Page 3

Although the heart averages 72 beats per minute, your body’s heart rate fluctuates multiple times

throughout the day. Several factors can affect heart rate, such as diet and exercise. Lets explore

some of these factors that affect YOUR hear rate.

1. Choose one member of your group and measure their heart rate by taking their pulse for 60

seconds. This will be their “resting” heart rate.

Take their resting heart rate two times and calculate

the average. Fill the data in below.

Resting heart rate 1:____________

Resting heart rate 2:____________

Resting heart rate average:_____________

2. Now have your group member do 30 jumping jacks. After the jumping jacks, have your group

member sit back in the chair as before and measure their heart rate. How has the heart rate changed?

Calculate % increase.

Your resting heart rate average (question 1):__________

Heart rate after 30 jumping jacks:___________

% increase:_______________

3. In the summer, you often go swimming in a lake or swimming pool. When you jump in for the

first time, the water is very cold. Before you jump in the pool or lake, your resting heart rate is 72

beats/min. Immediately after jumping into the pool, your heart rate becomes 52 beats/min. How has

your heart rate changed? Calculate % decrease.

Resting heart rate: 72 beats/min

Heart rate after jumping into cold water: 52 beats/min

% decrease:____________
