Rhythm of the Heart

45 minutes

Grade level: Lessons for K-2

Big idea

Students explore their heartbeats and the heart rates of different animals in this lesson that integrates music and science.

In the Film

In Superhuman Body, James Garrett realized something was wrong when he started getting tired and needed to rest more often.

Eventually he learned that he had aortic stenosis, which meant enough blood wasn’t getting pumped to the rest of his muscles and organs to keep his body working properly. Engineers designed a valve to help his heart pump blood efficiently again.


  1. Students will compare fast and slow heart rates.
  2. Students will predict the speed of a heart rate based on the size of an animal.
  3. Students will explain what a heartbeat is.
