Activity 22B: The Heart: A Muscle
In today's activity, students are comparing the muscles in their hand, forearm, and shoulder to the muscle that makes up their heart. Students are trying to pump water the same number of times as their heart beats in one minute. Then, students are comparing the volume of water pumped to the volume of blood that the average heart pumps for a person of their height.
Homework: Review the vocabulary terms: vein, artery, heart
