This document outlines a lesson plan for teaching 9th standard biology students about the passage of food through the alimentary canal. The 40 minute lesson will use lecture, group discussion, and questioning to develop students' factual, conceptual, procedural, and metacognitive knowledge of the topic. Students will watch a video depicting the passage of food and label a diagram of the alimentary canal, which includes the mouth, esophagus, stomach, small intestine, and large intestine. The lesson aims to build students' understanding of the different parts of the alimentary canal and their roles in digestion.
