This unit of study focuses on the human circulatory system. The links in this unit direct students
to pages that present many aspects of the system including the heart, the movement of blood, and the vessels.
In addition, the unit includes sites for viewing open heart surgery and virtual dissections as well as
sites for learning about and diagnosing heart conditions. Finally, the unit incorporates information for
maintaining a healthy heart.
This unit was designed for sixth grade students. Since Michigan's curriculum calls for the dissection of
animal hearts in the sixth grade, I assume students at this level will find the unit to be relevant and interesting.
