Student lesson
- Earth spins once in about 24 hours.
- It spins west to east.
- The Sun seems to rise in the east.
- Time zones follow longitude.
Words to know
spinning around an axis
the imaginary line through the poles
a region sharing the same clock time
a circular streak made by stars in a long photo
1. Discover: The long-exposure photo
Ms Frimpong shows a long-exposure photo of the night sky: the stars have drawn bright circles around a central point. “Earth is turning, so the stars seem to move,” she says. “The centre point is above the pole.”
Think: Which way is Earth spinning?
2. Understand: Rotation
Idea 1: Spin
Earth rotates on its axis once in about 24 hours, from west to east. At the equator the surface moves at about 1,670 km/h, but we do not feel it because everything moves together.
Idea 2: Apparent motion
Because Earth turns eastward, the Sun, Moon and stars seem to move east to west. In a long photo, stars make circular star trails around the pole.
Idea 3: Time
The world is divided into time zones about 15° of longitude wide, one hour apart, because Earth turns 360° in 24 hours.
3. Worked examples
Example 1 (I show you): Calculate
Degrees per hour.
- 360°.
- 24 hours.
- 15°.
Answer: 15° per hour.
Example 2 (We do it together): Explain
Apparent motion.
- Earth turns east.
- Sky seems west.
- Relative.
Answer: Relative motion.
Example 3 (You try): Find
Time difference.
Show the steps and answer
- Two zones.
- 30°.
- 2 hours.
Answer: Use 15°.
Did you know?
Jean Foucault’s pendulum in 1851 proved Earth rotates because the swinging plane slowly turned.
Why this matters
Rotation sets our day, our clocks and the pattern of winds and currents.
4. Explore: Spinning globe
Spin a globe (or a ball) under a lamp, mark your town with a sticker and track when it enters and leaves the light.
- Place the lamp.
- Mark your town.
- Spin slowly.
- Note day and night.
Think about it: what did you notice?
What did you notice? My town moved from light to dark as the globe turned.

If a learner struggles
- Find the misconception: “The Sun goes around Earth every day.” Earth rotates.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain rotation.
- 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 Earth’s rotation. You do not need to be an expert to help.
- Watch sunrise.
- Ask “Why does it rise?”
- Use a globe.
- 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: define rotation; link rotation to day and night; explain time zones; describe evidence.
Prerequisite knowledge. Grade 5 ideas: the Solar System, the Sun, Earth and Moon motions and models.
Materials. Globe, lamp, stickers. 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. Darken the room.
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). Spin a globe and ask, “What does this model show?”
Explanation (10 min). Teach rotation.
Guided activity (10 min). Learners model.
Independent activity (10 min). Learners calculate.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which way is it turning? How long?
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 goes around Earth every day.” 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 rotation. 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.
