The Digestive System: Where Does Food Go?

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a lab exploration that first has individuals cut yarn to represent the different parts of their digestive systems. They then examine the role of each component using common household materials.
