Lesson Plan

• Describe the differences between active and passive immunity.
• Explain how natural immunity differs from artificial immunity.
• Compare the duration of protection and memory formation for each immunity type.
• Evaluate real‑world examples and classify them as active/passive and natural/artificial.
• Apply the classification to novel scenarios in a short written response.

• Projector and slide deck
• Printed comparison‑table handout
• Whiteboard and markers
• Student worksheets with case‑study cards
• Index cards for exit‑ticket quiz
• Flowchart diagram of the four immunity categories

Start with the question, “How does your body protect you after a vaccination compared to after receiving antibodies from your mother?” Review students’ prior knowledge of antibodies, then outline today’s success criteria: students will differentiate active vs. passive and natural vs. artificial immunity and provide appropriate examples.

1. Do‑Now (5'): Students match immunity types to examples on a quick worksheet.
2. Mini‑lecture (10'): Teacher presents the two classification schemes using slides and the flowchart diagram.
3. Guided comparison (10'): Whole‑class fill‑in of the comparison table on the board, highlighting source, memory, duration, and examples.
4. Group activity (15'): Case‑study cards – each group determines whether a scenario is active/passive and natural/artificial and justifies their reasoning.
5. Think‑Pair‑Share (5'): Discuss why vaccines represent active artificial immunity.
6. Formative check (5'): Exit ticket – write one concise definition for each of the four immunity categories.

Recap the key distinctions between the four immunity types and check understanding through the exit tickets. Assign a short homework task: research a specific vaccine and identify whether it provides active artificial immunity and why.
