Student lesson
- The Moon formed about 4.5 billion years ago.
- It has craters and maria and almost no atmosphere.
- Its gravity is about one sixth of Earth’s.
- It causes tides.
Words to know
the idea that a Mars-sized body hit Earth to form the Moon
dark plains on the Moon
rise and fall of sea level
an extremely thin atmosphere
1. Discover: The Apollo footprints
Footprints left by Apollo astronauts in 1969 are still on the Moon because there is no wind or water to erase them. “The Moon has almost no atmosphere,” says Mr Armah. “So nothing weathers the surface.”
Think: How long might they last?
2. Understand: The Moon
Idea 1: Origin
The giant impact hypothesis says a Mars-sized body hit the young Earth about 4.5 billion years ago and the debris formed the Moon.
Idea 2: Features
The Moon is about 3,474 km wide (a quarter of Earth’s width) and 384,400 km away. It has craters, dark maria and a very thin exosphere. Temperatures range from about −170°C to 120°C.
Idea 3: Effects
The Moon’s gravity causes ocean tides and helps stabilise Earth’s tilt. Twelve astronauts have walked on it between 1969 and 1972. New missions are planned.

Show the steps and answer
- No air.
- No weather.

Answer: Preserved.
Did you know?
The Moon is moving away from Earth by about 3.8 centimetres every year.
Why this matters
The Moon influences our oceans, calendars and culture.
4. Explore: Crater lab
Drop marbles into a tray of flour dusted with cocoa from different heights, measure crater widths and compare with the Moon’s craters.
- Fill the tray.
- Dust with cocoa.
- Drop marbles.
- Measure.
Think about it: what did you notice?
What did you notice? Higher drops made larger craters.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “The Moon makes its own light.” Reflects.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Describe the Moon.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child studies the Moon. You do not need to be an expert to help.
- Watch the Moon.
- Ask “How did it form?”
- Mind flour.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: describe the Moon; explain its origin; explain tides; summarise exploration.
Prerequisite knowledge. Grade 5 ideas: the Solar System, the Sun, Earth and Moon motions and models.
Materials. Tray, flour, cocoa, marbles. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Cover tables.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a Moon photo and ask, “What marks are these?”
Explanation (10 min). Teach the Moon.
Guided activity (10 min). Learners model craters.
Independent activity (10 min). Learners explain.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How did it form? What does it affect?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “The Moon makes its own light.” Reflects.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Describe the Moon. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
