We Are Teachers

Kids need to learn how their bodies work and how to take care of them. Suffice it to say that the heart and circulatory system are a big part of that. Learning about the circulatory system through fun activities is hands-on—check your pulse to help students understand what’s happening—and it’s conceptual.

These hands-on, interactive activities teach and reinforce learning about the circulatory system. They’ll help kids learn how important it is to take care of their one and only heart!

1. Reveal the circulatory system
