Lesson 1: Introduction: planets & their properties
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
Write down everything you already know about planets & their properties. Then check against the key terms: key terms from planets & their properties. Use a mini-whiteboard or paper.
Main Content (35 minutes)
Parent/Teacher Guide: Before lesson: Read the script below. Pre-teach key vocab: key terms from planets & their properties. If stuck: Re-read the revision notes (link above), then break the content into smaller steps. Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins): Mins 0-5 - Hook: "Today: planets & their properties. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Astronomy because the ideas here recur across the spec." Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words. Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance. Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look
Start with the revision notes summary, then attempt: explain the key ideas of planets & their properties
Plenary (5 minutes)
Check Out
Your student states one thing they learned and one question they still have about planets & their properties.
Lesson 2: Core Concepts: planets & their properties
Duration: 50 minutes
Starter Activity (5 minutes)
Review Previous Lesson
Quick recap: write 3 key points from Lesson 1 on planets & their properties. Check them against the notes below.
Main Content (35 minutes)
Key Fact: Mercury is the smallest planet, closest to the Sun, with no atmosphere and extreme temperature variations
Key Fact: Venus has a thick CO2 atmosphere causing a runaway greenhouse effect; it rotates retrograde
Key Fact: Earth is the only planet known to support life, with liquid water and a nitrogen-oxygen atmosphere
Key Fact: Mars has a thin CO2 atmosphere, the largest volcano (Olympus Mons) and canyon (Valles Marineris) in the Solar System
Key Fact: Jupiter is the largest planet with the Great Red Spot (a persistent anticyclonic storm) and at least 95 moons
Key Fact: Saturn is known for its prominent ring system made of ice and rock particles

Explain Back
Your student teaches the key points back to you without looking. Fill any gaps immediately.
Lesson 3: Application: planets & their properties
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
Recall the key terms: key terms from planets & their properties. Define each in one sentence.
Main Content (35 minutes)
Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.
Work through the practice questions on the revision notes page for this topic.

Error Review
Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.
Lesson 4: Exam Practice: planets & their properties
Duration: 50 minutes
Starter Activity (5 minutes)
Command Words
Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).
Main Content (35 minutes)
Exam-Style Question
Attempt a past-paper style question on planets & their properties from the exam board past paper finder (see Resources), then mark it against the scheme.
Exam Tips: Use comparative language: 'whereas', 'compared to', 'in contrast to' | Know at least one unique feature per planet — exam questions often ask about specific planets | Venus is sometimes called Earth's 'twin' due to similar size, but conditions are very different | For Edexcel, be prepared to compare and contrast terrestrial vs giant planets in a table
Common Errors: ✗ Venus is the hottest planet because it is closest to the Sun ✓ Mercury is closest to the Sun, but Venus is hottest due to its thick CO2 atmosphere and runaway greenhouse effect ✗ Saturn's rings are solid ✓ Saturn's rings are made of countless particles of ice and rock, ranging from tiny grains to house-sized fragments ✗ All planets rotate in the same direction ✓ Venus rotates retrograde (clockwise from above), and Uranus rotates on its side (~98° tilt)
Stretch & Challenge (Grade 8-9):
Synoptic links: explain how planets & their properties connects to another Astronomy topic you have studied
Real-world: research one real-world use or example of planets & their properties
Critical: "What are the limitations of the models used in planets & their properties?"
Plenary (5 minutes)
