Science Projects, Lesson Plans and Experiments
Digestion Simulation Have students work in groups of 2-3. Each group gets a quart size zip-lock bag (stomach), cracker and piece of banana (food), and a few drops of water (digestive juices). Seal the bag and take turns kneading the bag like your stomach does to your food. After a while the cracker and banana become a liquidy mixture. This gives kids a hand-on explanation of how solid food as they know it is not utilized by the body that way. |
