Lesson Plan
Grade: Date: 25/02/2026
Subject: Biology
Lesson Topic: Identify the main regions of the alimentary canal and associated organs: mouth, salivary glands, oesophagus, stomach, liver, gall bladder, pancreas, small intestine, large intestine, rectum and anus.
Learning Objective/s:
  • Identify and label each region and accessory organ of the human alimentary canal.
  • Explain the primary function of each part in digestion and absorption.
  • Compare mechanical and chemical digestion processes across the tract.
  • Describe how bile and pancreatic secretions assist digestion.
  • Summarise the complete pathway of food from ingestion to elimination.
Materials Needed:
  • Projector and screen
  • PowerPoint/Google Slides presentation
  • Printed diagram handouts (blank and labelled)
  • Worksheet with labeling activity
  • Organ‑function cards
  • Short animation video of digestion
  • Whiteboard and markers
  • Exit‑ticket quiz cards
 Introduction:
Imagine swallowing a piece of bread and tracing its journey through every organ of the digestive system. Building on students’ prior knowledge of basic digestion, the teacher will state that today they will map that journey and understand each part’s role. Success will be measured by accurate labeling of the canal and clear explanations of each organ’s function.
Lesson Structure:
  1. Do‑now (5'): Students label a blank alimentary‑canal diagram on the worksheet.
  2. Mini‑lecture with slides (10'): Overview of each region and its main functions, highlighting mechanical vs chemical digestion.
  3. Group activity (10'): Match organ cards to function cards and place them on a large poster of the canal.
  4. Video & discussion (8'): Watch a 3‑minute animation of food passage; discuss key points and answer quick‑fire questions.
  5. Formative check (7'): Exit‑ticket (3 short questions) to assess understanding; teacher reviews common misconceptions.
Conclusion:
The teacher recaps the journey of food, emphasizing where mechanical and chemical digestion occur and the role of accessory organs. Students complete an exit‑ticket that asks them to list the three main functions of the small intestine. For homework, learners create a one‑page flowchart showing the sequential steps of digestion with brief notes on each organ.
