Lesson 1: Introduction: Rock Deformation Stress

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

3 quick questions to activate prior knowledge about rock deformation stress. Use mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read script below. Prepare materials. Pre-teach key vocab: Rock Deformation Stress.
If stuck: See Troubleshooting below. Break into smaller steps.
Extension: See Stretch & Challenge section.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: Rock Deformation Stress. Goal: by the end you can ✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile), using the method shown step by step. Connects to the previous lesson in this unit because you'll reuse its method throughout today's work."
Mins 5-15 - Direct Instruction: 1) Define: "Rock Deformation Stress is..." 2) Key principle: "Most important:..." 3) Draw diagram, label live. 4) Real example: "Like ✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile) - a real example worked through in full..."
Mins 15-25 - Guided Practice: Ex1: Teacher models. Ex2: Student tries with guidance. Ex3: Student independent.
Mins 25-35 - Independent Practice: 3-5 questions. Immediate feedback.
Worked Example 1: Basic

Q: ✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile)

  1. What is asked? Explain
  2. Recall knowledge:
  3. Apply: ✗ Normal faults form under compression ✓ Normal faults form under TENSION, the hanging wall moves DOWN. Reverse faults form under compression, the hanging wall moves UP ✗ Joints and faults are the same thing ✓ Joints are fractures with NO movement; faults are fractures WITH movement along the plane
  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: ✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile)

  1. Break down: Separate parts?
  2. Solve each: ✗ Normal faults form under compression ✓ Normal faults form under TENSION, the hanging wall moves DOWN. Reverse faults form under compression, the hanging wall moves UP ✗ Joints and faults are the same thing ✓ Joints are fractures with NO movement; faults are fractures WITH movement along the plane
  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: ✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile)

  1. Read data: Axes, units, scale
  2. Patterns: Trends, anomalies
  3. Explain: Why? Using rock deformation stress
  4. Conclude: Evidence-based

Common Questions & Troubleshooting

Q: "Why does Rock Deformation Stress work this way?"
A: Analogy: "✗ All rocks fracture under stress ✓ Rocks near the surface fracture (brittle), but at depth under high temperature and pressure they fold (ductile)". 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.
