Lesson Plan
Grade: Date: 25/02/2026
Subject: Biology
Lesson Topic: discuss the biological, social and economic factors that need to be considered in the prevention and control of cholera, malaria, TB and HIV (details of the life cycle of the malarial parasite are not expected)
Learning Objective/s:
  • Describe the biological, social and economic factors influencing control of cholera, malaria, TB and HIV.
  • Analyse how these factors affect the selection of prevention and control strategies.
  • Compare and evaluate appropriate public‑health interventions for each disease.
  • Apply knowledge to propose a community‑based control plan for a selected infection.
Materials Needed:
  • Projector and screen for slides
  • Printed handout summarising disease factors
  • Whiteboard and markers
  • Case‑study worksheets
  • Internet access for short video on WASH and vector control
  • Flip chart for group brainstorming
 Introduction:
Begin with a striking image of a cholera outbreak and ask students what immediate actions come to mind. Recall prior learning on disease transmission and the role of public health measures. Explain that by the end of the lesson they will be able to identify and evaluate the biological, social and economic drivers that shape control strategies for cholera, malaria, TB and HIV.
Lesson Structure:
  1. Do‑now (5') – quick quiz on modes of transmission for the four diseases.
  2. Mini‑lecture (10') – overview of biological, social, economic factors using the comparative table.
  3. Small‑group analysis (15') – each group receives a disease case study and lists key factors and appropriate interventions.
  4. Whole‑class sharing (10') – groups present findings; teacher highlights similarities and differences.
  5. Interactive simulation (10') – allocate limited resources across diseases and discuss trade‑offs.
  6. Exit ticket (5') – students write one critical factor for each disease and justify its importance.
Conclusion:
Summarise how biological, social and economic contexts determine the choice of control measures. Collect the exit tickets to gauge understanding and clarify any misconceptions. Assign homework: research a recent real‑world outbreak and write a brief paragraph linking the three factor categories to the response.
