SciGirls | Heart to Heart

The heart is the hardest working muscle in the human body, pumping out oxygenated, nutrient-rich blood with every beat.

In this activity, students will compare ways to measure heart rate (and build their own stethoscopes!) to learn how exercise affects heart rate. (Grades: 5-8)
