SUMMARY: Children get clued in on the chemical reactions that occur when they prepare, analyze, and digest their food. The class gets cooking with a color-changing solution display. Children divide common kitchen activities into chemical and physical reactions. A balloon blow-up demonstration helps them discover that yeast makes bread rise. Children test food samples in search of nutrients, starch, and protein. They discover what happens after they eat and digest nutrient-rich foods with their own Digestor Inspector Take-Home.
EDUCATIONAL VALUE: Children are introduced to the differences between chemical and physical reactions. The instructor demonstrates how yeast feeds on sugars to produce a gas-filled balloon. The children test food samples for starch and protein and learn that certain foods help us grow, develop, and function. They familiarize with digestion— the process that occurs after they eat. The hands-on, clear digestive-track model extends this concept at home!
