Lesson Plan

• Describe what computer modelling is and how it differs from manual human modelling.
• Identify at least three advantages of computer modelling.
• Identify at least three disadvantages of computer modelling.
• Compare computer modelling and human modelling using a comparison table.
• Evaluate situations where computer modelling is the preferred approach.

• Projector and screen
• Printed handout with the comparison table
• Laptops with simple modelling software (e.g., NetLogo or spreadsheet simulation)
• Whiteboard and markers
• Sticky notes for group brainstorming

Begin with a quick question: “How would you safely test a volcanic eruption or a car crash?” Students share ideas, linking to prior knowledge of simulations. Explain that today they will explore how computers can model such scenarios and what trade‑offs exist. Success criteria: students will be able to list and compare key advantages and disadvantages of computer modelling.

1. Do‑now (5') – Think‑pair‑share: list real‑world problems that are risky to test physically.
2. Mini‑lecture (10') – Define computer modelling, show a flowchart diagram and discuss its components.
3. Group activity (15') – Using laptops, explore a pre‑built traffic‑flow model; note speed, cost and safety aspects.
4. Whole‑class discussion (10') – Create a Venn diagram of advantages vs. disadvantages on the board.
5. Comparison table analysis (10') – Complete a worksheet matching aspects to advantages/disadvantages.
6. Exit ticket (5') – Write one scenario where computer modelling is preferable and one where human modelling is better.

Recap the main benefits (speed, cost, safety) and drawbacks (data quality, complexity, ethical issues) of computer modelling. Collect exit tickets to gauge understanding and assign homework: research a real‑world case study of computer modelling and prepare a short summary for the next lesson.
