This is a great powerpoint to supplement your heart unit. The circulatory system can be difficult to understand but this kid friendly story of the journey of a blood drop helps children understand with its MANY visuals. It also includes a quiz at the end. If you are looking for other activities to supplement your unit see my store for my nonfiction heart unit! If you decide to buy my unit this powerpoint is included in the unit so do not buy both. I teach this unit during Heart Healthy Awareness month.
