Lesson 1: Introduction: the sun

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about the sun. Then check against the key terms: GCSE Astronomy Exam Tips — The Sun. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: GCSE Astronomy Exam Tips — The Sun.
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: the sun. 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 the sun

Plenary (5 minutes)

Check Out

Your student states one thing they learned and one question they still have about the sun.

Lesson 2: Core Concepts: the sun

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on the sun. Check them against the notes below.

Main Content (35 minutes)

Key Fact: The Sun is a G-type main-sequence star (G2V) with surface temperature ~5,500°C and core temperature ~15 million°C
Key Fact: Energy is produced by nuclear fusion: hydrogen nuclei fuse to form helium via the proton-proton chain
Key Fact: The Sun's layers: core (energy production), radiative zone, convective zone, photosphere (visible surface), chromosphere, corona
Key Fact: Sunspots are cooler, darker regions on the photosphere caused by magnetic field concentrations
Key Fact: The solar cycle lasts approximately 11 years, with sunspot numbers rising and falling
Key Fact: The solar wind is a stream of charged particles (mainly protons and electrons) flowing outward from the Sun

Practice (10 minutes)

Q: explain the key ideas of the sun

Answer:

Plenary (5 minutes)

Explain Back

Your student teaches the key points back to you without looking. Fill any gaps immediately.

Lesson 3: Application: the sun

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: GCSE Astronomy Exam Tips — The Sun. 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.

Plenary (5 minutes)

Error Review

Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.

Lesson 4: Exam Practice: the sun

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 the sun from the exam board past paper finder (see Resources), then mark it against the scheme.

Exam Tips: The proton-proton chain is the specific fusion process in the Sun — don't just say 'nuclear fusion' | Sunspots appear dark because they are cooler (~3,500°C) than surrounding photosphere (~5,500°C) | The solar cycle is ~11 years from minimum to minimum (or maximum to maximum) | AQA expects you to know the Sun's internal structure layers in order
Common Errors: ✗ The Sun burns fuel like a fire ✓ The Sun produces energy by nuclear fusion — hydrogen nuclei fuse to form helium, releasing energy via E=mc² ✗ Sunspots are dark because they emit no light ✓ Sunspots are dark because they are cooler (~3,500°C) than the surrounding photosphere (~5,500°C) — they still emit light, just less ✗ The solar cycle lasts exactly 11 years ✓ The solar cycle is approximately 11 years — it varies between about 9 and 14 years
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how the sun connects to another Astronomy topic you have studied
  • Real-world: research one real-world use or example of the sun
  • Critical: "What are the limitations of the models used in the sun?"

Plenary (5 minutes)

Assessment Criteria
  • Got it: Confident explanation + correct worked examples
  • Getting there: Main points OK, needs support with detail
  • Not yet: Confused on key concepts - re-run Lesson 2
