Lesson 1: Introduction: Wave Properties

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

3 quick questions to activate prior knowledge about wave properties. Use mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read script below. Prepare materials. Pre-teach key vocab: Wave Properties.
If stuck: See Troubleshooting below. Break into smaller steps.
Extension: See Stretch & Challenge section.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: Wave Properties. Goal: by the end you can in transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down, 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: "Wave Properties is..." 2) Key principle: "Most important:..." 3) Draw diagram, label live. 4) Real example: "Like In transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down. - 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: In transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down.

  1. What is asked? In
  2. Recall knowledge:
  3. Apply: In longitudinal waves, the vibrations are parallel to the direction of energy transfer. They consist of compressions (regions of high pressure) and rarefactions (regions of low pressure).
  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: In transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down.

  1. Break down: Separate parts?
  2. Solve each: In longitudinal waves, the vibrations are parallel to the direction of energy transfer. They consist of compressions (regions of high pressure) and rarefactions (regions of low pressure).
  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: In transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down.

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

Common Questions & Troubleshooting

Q: "Why does Wave Properties work this way?"
A: Analogy: "In transverse waves, the vibrations are perpendicular to the direction of energy transfer. Imagine shaking a rope up and down — the wave travels along the rope but the rope moves up and down.". 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 P22: 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 P22 questions: Underline the command word, count the marks (one mark per point expected), and answer in the format the command word demands.

Board Notes & Revision Links

This lesson is examined by: AQA 8463 | Edexcel 1PH0 | OCR J249 | CCEA units. Tier and paper details vary - always check your board's current specification.

Follow-up revision: P21-wave-properties on GCSE Revise (notes, flashcards and auto-graded target tests for this exact topic).

Amplitude Wavelength (λ) Crest Trough

✏️ Draw-Along Instructions

Parent/teacher: Draw a horizontal dashed line (rest position). Draw a smooth sine wave above and below it. Label the height from rest to crest as "amplitude". Label the distance between two crests as "wavelength (λ)".

Display the reference diagram (or draw it live) while pupils copy. Check each label as it is added.
