For most of history, scientists weren’t quite sure why our hearts were
beating or even what purpose they served. Eventually, we realized that
these thumping organs serve the vital task of pumping clean blood
throughout the body. But how? Edmond Hui investigates how it all works
by taking a closer look at the heart’s highly efficient ventricle
system.
Teaching students how the heart works is a difficult task. This TED-Ed video makes it much easier. In less than 5 minutes students (and teachers!) may gain a much better understanding of how the heart works. If you are able to get hearts from pigs or sheep to dissect students will quickly gain a clear understanding of exactly how the heart works.
You will also find additional resources, including: a link to the first TEDx talk where a student from Teddington School, a secondary school in England, explains how he learned this by working with Dr. Hui as a mentor, questions (both multiple choice and open reponse), and an online forum.
