1. Key Ideas

No new content. This lesson deepens your understanding of L06–L10 through patient case studies, analogy analysis, worked examples of increasing difficulty, and a Band 6 extended response. You will classify disease types, trace mechanisms, and dismantle the most common IQ2 misconceptions.

Classify disease types using mechanism, not just label
Link genetic, environmental, and nutritional factors in multifactorial disease (Type 2 diabetes, cancer)

2. Success Criteria

By the end, you should be able to:

Classify disease types using mechanism, not just label
Explain why the same gene mutation can have variable outcomes (penetrance, expressivity)
Distinguish cause, risk factor, and susceptibility

3. Key Terms

attempt to identify whatbiologically wrong with the stated diagnosis

Thereno tricks — the errors reflect real misconceptions students make in HSC exams

Thisa lifestyle disease — you caused it by eating poorly and not exercising

Cancercaused by lifestyle choices — you must have done something to cause this

the correct termsusceptibility, not certainty

Goitrecaused by TOO LITTLE iodine, not too much

5. Short Answer Questions

1. Explain this lesson goal in your own words: "Classify disease types using mechanism, not just label". Use one specific example from the lesson.

Band 32 marks

2. Apply this idea to a new example: "Explain why the same gene mutation can have variable outcomes (penetrance, expressivity)". Show your reasoning clearly.

Band 43 marks

3. Analyse why this idea matters for understanding Causes Mastery — Diagnosing Disease Types, Mechanisms and Misconceptions: "Distinguish cause, risk factor, and susceptibility".

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Causes Mastery — Diagnosing Disease Types, Mechanisms and Misconceptions but does not use evidence or reasoning.

Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.

C. Ignore the command word

D. Skip examples and evidence

2. Which answer would show stronger understanding of Causes Mastery — Diagnosing Disease Types, Mechanisms and Misconceptions?

A. An answer with accurate terms and reasoning

B. A copied definition only

C. A single-word response

D. An answer with no example

3. What should you do if a question asks you to explain?

A. Link the idea to a reason or cause

B. List unrelated facts

C. Only draw a diagram

D. Write the shortest possible answer

8. Success Criteria Proof

Finish with evidence that you can do each success criterion.
