Digestive System Simulation

What do a sandwich bag and a mouth have in common? Your classes are about to find out in a hands-on lesson that has groups build models of the digestive system. Using a little imagination, learners use everyday materials to create a three-dimensional model that simulates the structure and function of the parts of the digestive system. They cap off their experience by helping a cracker through their simulation models.
