My STEAM project for this semester focuses on red blood cells (RBCs) and hemoglobin, more specifically how the most common type of anemia affects RBCs. The RBC (displayed as PlayDoh) contains hemoglobin (displayed as ribbons). Each ribbon color represents the four globular protein subunits that make up a hemoglobin molecule. Within each subunit is one heme molecule containing iron (displayed as a red googly eye). The bottom of the illustration shows the amount of RBCs in a healthy individual compared to fewer amounts of RBCs in a person who is anemic.
