The PBS series RED GOLD: THE EPIC STORY OF BLOOD examines blood from several angles, including its mystical and magical elements, its impact on war and its political implications. Underlying all of these themes is the fact that blood is a life force, and our knowledge and understanding of it has helped save countless lives. Central to our understanding of blood is its composition and this lesson will demonstrate the composition of whole blood, with students researching blood's components. They will use their math skills to recreate a model of whole blood using commonly found food items.
