Subject: Biology
Lesson Topic: Describe coronary heart disease in terms of the blockage of coronary arteries and state the possible risk factors including diet, smoking and lack of exercise.
Learning Objective/s:
  • Describe how atherosclerosis leads to coronary artery blockage.
  • Explain the impact of reduced coronary blood flow on heart function.
  • Identify the major modifiable risk factors for CHD (diet, smoking, inactivity).
  • Analyse how lifestyle changes can reduce CHD risk.
  • Evaluate preventive measures for maintaining healthy coronary arteries.
Materials Needed:
  • Projector and screen
  • PowerPoint slides with diagrams of arteries and plaques
  • Printed handout of the risk‑factor table
  • Blank worksheets for case‑study analysis
  • Markers and whiteboard
  • Model of a heart (optional)
 Introduction:
Begin with a short video clip showing a heart beating followed by a graphic of a blocked artery to capture interest. Ask students what they already know about heart health and the role of blood vessels. Explain that today they will learn how blockages develop, which lifestyle choices increase risk, and they will be able to list preventive actions by the end of the lesson.
Lesson Structure:
  1. Do‑now (5'): Quick quiz on the basic circulatory system; teacher checks answers.
  2. Teacher input (10'): Define CHD and atherosclerosis, show diagram of normal vs. blocked coronary artery.
  3. Group activity (12'): Pairs analyse the risk‑factor table and create a poster summarising how each factor contributes to plaque formation.
  4. Case‑study discussion (10'): Review a short patient scenario with chest pain, link symptoms to reduced oxygen supply.
  5. Preventive measures brainstorming (8'): Whole‑class list of lifestyle changes; compare with textbook list.
  6. Exit ticket (5'): Students write one personal action they will adopt to lower CHD risk.
Conclusion:
Summarise that CHD results from arterial blockage caused by atherosclerosis and is driven by diet, smoking and inactivity. Highlight the preventive strategies discussed and remind students to complete the homework worksheet on personal risk assessment. Collect exit tickets as a quick check of understanding.
