A Walk Through the Gut

This simulation helps learners understand what happens to food as it passes through the digestive system. The learner has a 3x5 index card representing food, which he / she carries to stations around the room. Each station creatively represents one of the organs of the digestive system. At each station, the learner is given a specific instruction to "digest" the index card and then instructed to "proceed to the next station." At the end of the simulation, learners form cooperative learning groups to analyze and apply the results of the simulation to the human digestive system. This lesson guide includes an alternate plan in which learners research and write the digestion directions as well as extensions and reinforcements.
