Student lesson
- The Sun seems to move east to west.
- This is caused by Earth’s rotation.
- It is highest at noon.
- Its path changes through the year.
Words to know
seeming, not real
where the sky meets the land
midday, when the Sun is highest
the compass direction of an object
1. Discover: The moving mark
Ama marks the edge of a shadow on the playground at 9, 12 and 3 o’clock. The marks form a line. “The Sun seems to move across the sky,” she says. “But really it is Earth that turns.” Her teacher calls it apparent motion.
Think: What would happen to the marks if Earth stopped turning?
2. Understand: Apparent motion
Idea 1: What we see
From Earth the Sun seems to climb from the horizon at sunrise, reach its highest point at noon and sink at sunset.
Idea 2: Apparent motion
This is apparent motion: the Sun looks as if it moves, but it is Earth that is rotating. It is like passing trees seen from a bus.
Idea 3: Tracking
We can track the Sun’s path by marking shadow tips each hour. Shadow direction and length show where the Sun is.
3. Worked examples
Example 1 (I show you): Explain
Sun seems to move.
- Earth rotates.
- Apparent.
- Not real.
Answer: It is apparent motion.
Example 2 (We do it together): Predict
Noon shadow.
- Sun high.
- Short shadow.
- Points away.
Answer: The shadow is shortest at noon.
Example 3 (You try): Track
Mark shadow tips.
Show the steps and answer
- Hourly.
- Line forms.
- Moves.
Answer: Shadow tips move in a curve.
Did you know?
For thousands of years people believed the Sun really went round Earth; Copernicus showed in 1543 that Earth moves.
Why this matters
Understanding apparent motion helped us discover that Earth rotates.
4. Explore: Shadow tracking
Mark the tip of a stick’s shadow every hour and record.
- Place a stick in the ground.
- Mark the shadow tip.
- Repeat each hour.
- Join the marks.
Think about it: what did you notice?
What did you notice? Shadows moved from west to east as the Sun moved east to west.

|---|---|---|---|
| O1 Describe the Sun’s path | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Explain apparent motion | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Track its position safely | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |

If a learner struggles
- Find the misconception: “The Sun moves round Earth.” Earth rotates.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain apparent motion.
- 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 tracks the Sun with shadows. You do not need to be an expert to help.
- Mark a shadow together.
- Ask “Why did it move?”
- Do not look at the Sun.
- 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 Sun’s path; explain apparent motion; track its position safely; link to time of day.
Prerequisite knowledge. Grade 3 Earth ideas: weather patterns, seasons and shadows.
Materials. Stick, chalk, ruler. 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. Find a sunny spot.
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 sun-path picture and ask, “What is moving?”
Explanation (10 min). Teach apparent motion.
Guided activity (10 min). Learners track.
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. Apparent or real? What moves?
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 Sun moves round Earth.” Earth rotates.
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. Explain apparent motion. 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.
