Student lesson
- The Moon orbits Earth.
- It has no light of its own.
- Its surface has craters and plains.
- Its gravity is weaker than Earth’s.
Words to know
an object that orbits a planet
a bowl-shaped dent on the Moon
the pull between objects
to do with the Moon
1. Discover: The moonlit night
Esi looks at the bright Moon. “Is it shining by itself?” she asks. “No,” says her uncle. “It reflects the Sun’s light.” Through binoculars she sees round dents, craters, and dark flat plains. “It looks like the surface of a dry desert,” she says.
Think: Why does the Moon seem to glow?
2. Understand: Moon
Idea 1: Earth’s satellite
The Moon is Earth’s only natural satellite. It orbits Earth about once every 27 days. It is about a quarter of Earth’s width.
Idea 2: The surface
The Moon has craters from meteor impacts, dark plains and mountains. It has almost no air or water, so it is silent and still.
Idea 3: Gravity
Moon gravity is about one sixth of Earth’s, so an astronaut can jump much higher there. Lunar means “of the Moon”.
3. Worked examples
Example 1 (I show you): Describe
Moon light.
- Reflects.
- Sun source.
- Not a lamp.
Answer: The Moon reflects sunlight.
Example 2 (We do it together): Describe
Craters.
- Dents.
- Meteors.
- Round.
Answer: Craters are impact dents.
Example 3 (You try): Compare
Gravity.
Show the steps and answer
- One sixth.
- Higher jumps.
- Lighter.
Answer: Moon gravity is weaker.
Did you know?
Footprints left by the Apollo astronauts in 1969 are still on the Moon because it has no wind to blow them away.
Why this matters
The Moon shapes tides and has inspired stories and science.
4. Explore: Crater model
Drop balls into flour in a tray to make craters.
- Fill a tray with flour and dust cocoa on top.
- Drop balls from different heights.
- Observe craters.
- Measure sizes.
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.” It 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 learns about the Moon. You do not need to be an expert to help.
- Watch the Moon together.
- Ask “What shape tonight?”
- Stay near home.
- 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.

Materials. Pencil, paper. 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. Choose a night.
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 is on it?”
Explanation (10 min). Teach the Moon.

Independent activity (10 min). Learners compare.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Reflects? Craters? Gravity?
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.” It 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.
