What’s In My Blood?

Grade level: Ages 5-10

Big idea

In the film Superhuman Body, we see inside the heart as it pumps blood throughout our bodies; and we discover the important role that white blood cells play in our health.

Activity overview

You’ll need some sweet materials to complete this model of our blood system. You can use the activity to not only better understand the kinds of cells in our blood, but also how your completed model can be a sensory tool that helps you relax and be more mindful.
