Lesson Plan

• Describe the main causes of vitamin D deficiency and iron deficiency.
• Explain the physiological effects of each deficiency on the body.
• Compare the health consequences of vitamin D deficiency versus iron deficiency.
• Interpret a summary table to identify key differences in causes and effects.

• Projector and screen
• PowerPoint slides with diagrams of vitamin D synthesis and haemoglobin comparison
• Handout containing the summary table
• Blank worksheets for cause‑effect matching activity
• Markers and chart paper for group mind‑maps

Begin with a quick poll: “What foods or habits help you get enough sunshine and iron?” Use responses to link prior knowledge of diet and health. State that today’s success criteria are to list causes, explain effects, and compare the two deficiencies.

1. Do‑now (5'): Students write one cause and one effect for each deficiency on sticky notes.
2. Mini‑lecture (10'): Teacher presents key causes/effects with diagrams, highlighting differences.
3. Guided practice (12'): Whole‑class analysis of the summary table; students annotate a copy.
4. Group activity (15'): Teams complete a cause‑effect matching worksheet and create a mind‑map on chart paper.
5. Check for understanding (5'): Quick quiz using Kahoot or show of hands.
6. Reflection (3'): Students write one thing they found surprising and one question they still have.

Recap the main causes and health impacts of vitamin D and iron deficiencies, emphasizing how lifestyle choices influence each. Collect exit tickets where learners state one personal action to prevent a deficiency. Assign homework: research a real‑world case study of either deficiency and prepare a brief summary.
