Worked Example 1: Basic

Q: ✗ The Moon produces its own light. ✓ The Moon reflects sunlight. The 'phases' are simply the changing portion of the Moon's sunlit hemisphere visible from Earth as the Moon orbits.

  1. What is asked? Explain
  2. Recall knowledge:
  3. Apply: ✗ The dark side of the Moon is always dark. ✓ The 'dark side' (far side) receives just as much sunlight as the near side — it is simply the side we never see from Earth due to tidal locking. Both sides experience day and night. ✗ Eclipses happen every new and full moon. ✓ Eclipses only occur when the Moon is near a node (where its orbit crosses the ecliptic) at new or full moon. The Moon's 5° orbital tilt means it usually misses alignment.
  4. Check: Check the units named in the question and sense-check the size of your answer.
  5. Answer: State the complete final answer.

Tip: "Show working - method marks > answer marks."

Worked Example 2: Multi-step

Q: ✗ The Moon produces its own light. ✓ The Moon reflects sunlight. The 'phases' are simply the changing portion of the Moon's sunlit hemisphere visible from Earth as the Moon orbits.

  1. Break down: Separate parts?
  2.

Both sides experience day and night. ✗ Eclipses happen every new and full moon. ✓ Eclipses only occur when th
  3. Combine: The parts chain: each answer feeds the next step of the question.
  4. Final answer: Evidence cited from the lesson content.
Worked Example 3: Data/Application

Q: ✗ The Moon produces its own light. ✓ The Moon reflects sunlight. The 'phases' are simply the changing portion of the Moon's sunlit hemisphere visible from Earth as the Moon orbits.

  1. Read data: Axes, units, scale
  2. Patterns: Trends, anomalies
  3. Explain: Why? Using lunar phases eclipses
  4. Conclude: Evidence-based

Common Questions & Troubleshooting

Q: "Why does work this way?"
A: Analogy: "✗ The Moon produces its own light. ✓ The Moon reflects sunlight. The 'phases' are simply the changing portion of the Moon's sunlit hemisphere visible from Earth as the Moon orbits.". Try re-draw or re-write the worked example from memory, then check it against the model answer.
Q: "Wrong answers on calculations."
A: Checklist: units? formula? calculator mode? sig figs?
Q: "Can't remember key terms."
A: Flashcards (term front, def+diagram back). Spaced repetition: day 1, 3, 7.
Q: "Exam wording confuses me."
A: Commands: Describe=what you see; Explain=reasons; Evaluate=pros/cons+judgement; Calculate=working+units.
Q: "Running out of time."
A: 1 mark/min. Skip hard, return. Attempt all - partial marks count.

Assessment Criteria

📝 Mark Scheme Guidance

How examiners mark L1: Read the command word carefully — State = one word/phrase (1 mark), Describe = pattern or detail (2 marks), Explain = reason with "because" (2–3 marks), Compare = similarities AND differences, Evaluate = both sides + conclusion. Method marks are awarded for correct working even if the final answer is wrong. Always show your working — unexplained answers score zero for AO2.

Success on L1 questions: Underline the command word, count the marks (one mark per point expected), and answer in the format the command word demands.
