Digestive Process Simulation Activity

In this lesson, students explore the digestive process through a hands-on activity. The teacher guides them to simulate digestion using toast, vinegar, and water, representing chewing, stomach acid, and water removal. Students learn how these steps correlate with the digestive system's functions. The lesson concludes with a discussion on the activity's representation of digestion and a homework assignment.
