In this activity, we'll put the pedal to the metal to get your heart pumping. One of the many reasons exercise is so important is because it strengthens the heart. Your heart is a muscle, and like other muscles, it gets stronger and more efficient when it is exercised. 


Let's first learn about your heart and how to take your own pulse. 


Activity Instructions

for Observers (Pre-K through 2nd Grade) and Explorers (3rd Grade through 5th Grade)

Head over to the Citi Bike station (anytime between May 17-23) on Kane St. (at Clinton Street), and find the stationary Super Science Citi Bike. 

1. Take your resting heart rate (also called your pulse):

  • Place the tips of your index, second, and third fingers (do NOT use your thumb) on the palm side of your other wrist, below the base of the thumb. Or, place the tips of your index and second fingers on your lower neck, on one side of your windpipe.

  • Press lightly with your fingers until you feel a pulsing beneath your fingers. This pulse is the blood moving inside the vessels beneath your skin. You might need to move your fingers around slightly up or down until you feel the pulsing.

  • Use a watch with a second hand or set your phone timer for 30 seconds. 

  • Count the beats you feel for 30 seconds. Double this number to get the number of beats per minute (bpm).

2. Enter your age and BPM into this calculator, and then enter your activity level. This will calculate your target heart rate range for exercise. 

3. Hop on the Super Science Stationary Citi Bike and pedal as fast as you can for 1 minute. Now measure your heart rate (the same way you measured your resting pulse). Did you reach your target heart rate? 

Turn It In

Post a picture of yourself on the Citi Bike onto Padlet, and let us know if you hit your target heart rate!
