Exploring the Heart: Students Dive into the Circulatory System Through Hands-On Discovery

On our Historic Downtown Campus 4th grade students in Beth Matlock and Nancy Salem’s ELA classes are diving into an engaging interdisciplinary study of the circulatory system, inspired by The Circulatory Story by Mary K. Corcoran. Through this unit, students are exploring the question, “What is a great heart, literally?” as they deepen their understanding of how the heart functions and how blood moves through the body.

To bring their learning to life, students constructed intricate blood vessel models, creatively representing the four key components of blood: plasma, platelets, white blood cells, and red blood cells. Using various materials, each student crafted a detailed key to identify the components, alongside clear explanations of their roles. From plasma, the liquid carrier, to red blood cells delivering oxygen, white blood cells defending against infection, and platelets aiding in clotting, students thoughtfully described each element’s importance.

This hands-on activity not only reinforced their scientific knowledge but also encouraged them to apply it in creative, meaningful ways. The blend of inquiry and model-building made for a truly enriching experience, inspiring curiosity and deeper learning.
