Heart Break

The heart beats 24 hours a day, seven days a week, 52 weeks a year. It pumps up to 2000L of blood throughout your body every day, is capable of fully autonomous operation, and will even continue to pump for a short while when removed from the body. In this lesson students will be challenged to research the symptoms of a variety of heart diseases and conditions and determine their effects on the heart. They will then modify the provided heart model to illustrate these effects.
