| Lesson Topic: Describe the structure and function of the heart including the muscular wall and septum, atria, ventricles, valves and associated blood vessels. |
Learning Objective/s:
- Describe the main structural components of the heart (myocardium, septa, atria, ventricles, valves, major vessels).
- Explain the function of each component in the pulmonary and systemic circulations.
- Trace the pathway of blood through the heart, naming the valves encountered.
- Compare the left and right ventricles in terms of wall thickness and pressure generation.
- Evaluate how damage to valves or septa affects cardiac efficiency.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint/Google Slides presentation with heart diagram
- Printable worksheet for labeling activity
- 3‑D heart model or virtual model
- Coloured markers or pens
- Exit‑ticket cards
|
Introduction:
Begin with a quick animation showing blood rushing through a beating heart to capture interest. Ask students what they already know about how blood moves through the body and remind them that the heart’s chambers and valves keep flow one‑way. State that by the end of the lesson they will be able to label the heart’s structures and explain the blood‑flow sequence.
|
Lesson Structure:
- Do‑now (5'): Students complete a short quiz on circulatory pathways from the previous lesson.
- Teacher input (10'): Present key structures using slides and the 3‑D model, highlighting myocardium, septa, atria, ventricles, valves, and major vessels.
- Guided practice (12'): Whole‑class walkthrough of the blood‑flow pathway; students label a blank diagram on their worksheets.
- Collaborative activity (10'): In pairs, students create a flow‑chart on poster paper showing each step and valve, then present to the class.
- Check for understanding (8'): Quick formative quiz via Kahoot or show‑of‑hands questions on valve function and ventricle differences.
- Consolidation (5'): Summarise key points and answer any lingering questions.
|
Conclusion:
Recap the sequence of blood flow and the role of each valve, reinforcing why the left ventricle has a thicker wall. Have students write one exit‑ticket response describing what would happen if a specific valve failed. Assign homework to complete a labeled heart diagram and answer two short‑answer questions from the exam practice sheet.
