Third Grade Talking Points
- "The digestive system is like a team of spies working together to break down food and extract nutrients."
- "The mouth is like the spy who collects information by tasting and chewing food."
- "The esophagus is like the secret tunnel that transports the food to the stomach without us even noticing."
- "The stomach is like the spy's headquarters where food gets mixed with special chemicals to break it down."
- "The small intestine is like the spy's secret lab where the nutrients from the food are absorbed into the bloodstream."
- "The large intestine is like the spy's garbage disposal, where water is absorbed and waste is prepared for elimination."
