Lesson Plan

• Describe the physiological effects of starvation, constipation, coronary heart disease, obesity, and scurvy.
• Explain the dietary causes that lead to each condition.
• Compare short‑term and long‑term health consequences of malnutrition.
• Apply knowledge to interpret a summary table of malnutrition effects.

• Projector and screen
• Whiteboard and markers
• Printed summary‑table handouts
• Flow‑chart diagram of malnutrition effects
• Student worksheets with case‑study scenarios
• Kahoot/quiz cards for exit ticket

Begin with a quick “what would happen if you only ate once a week?” brainstorm to activate prior knowledge. Highlight that nutrition impacts many body systems and that today’s focus will be on extreme outcomes. State that students will be able to identify causes, effects, and health risks for five key malnutrition conditions by the end of the lesson.

1. Do‑now (5') – Students list immediate symptoms they think occur when food is scarce.
2. Mini‑lecture (10') – Teacher presents the five conditions using the flow‑chart diagram.
3. Guided analysis (12') – In pairs, pupils examine the summary table and match dietary causes to physiological effects.
4. Case‑study activity (10') – Groups receive a scenario (e.g., chronic low‑fiber diet) and create a cause‑effect chart.
5. Whole‑class debrief (8') – Groups share charts; teacher corrects misconceptions and reinforces key points.
6. Formative quiz (5') – Kahoot/exit ticket questions recap the main causes and signs of each condition.

Summarise how inadequate or excessive nutrition leads to specific health problems, linking back to the initial brainstorm. Students complete an exit ticket naming one preventive dietary change for each condition. Assign homework: research a real‑world example of one malnutrition effect and prepare a short paragraph.
