Student lesson
- The Sun rises in the east and sets in the west.
- Day length changes with the season.
- Time differs around the world.
- Some animals are nocturnal.
Words to know
when the Sun first appears
when the Sun disappears
active at night
active in the day
1. Discover: The owl and the farmer
Papa Yaw rises at sunrise to farm. By sunset he is home. Outside, an owl wakes and starts to hunt. “The farmer is diurnal and the owl is nocturnal,” says Yaa. When her aunt phones from London in the evening, Yaa asks why her time is different. “Because the Sun reaches different places at different times,” her teacher says.
Think: Why is the time different in London?
2. Understand: Day and night
Idea 1: Sunrise to sunset
The Sun appears to rise in the east at sunrise, is highest at noon and sets in the west at sunset. This is caused by Earth’s rotation.
Idea 2: Around the world
Because Earth is round, when it is day in one place it is night in another. The world is divided into time zones so clocks match local daylight.
Idea 3: Living things
Diurnal animals such as chickens are active in daytime. Nocturnal animals such as owls and bats are active at night. Plants open and close with daylight.
3. Worked examples
Example 1 (I show you): Direction
Sunrise.
- East.
- Appears.
- Rises.
Answer: The Sun rises in the east.
Example 2 (We do it together): Direction
Sunset.
- West.
- Disappears.
- Sets.
Answer: The Sun sets in the west.
Example 3 (You try): Classify
Owl.
Show the steps and answer
- Active at night.
- Hunting.
- Nocturnal.
Answer: Owls are nocturnal.
Did you know?
Near the poles there are weeks in summer when the Sun never sets and weeks in winter when it never rises.
Why this matters
Understanding day and night helps us plan our lives and understand animals.
4. Explore: Day and night diary
Record the times of sunrise and sunset for a week and compare to clock times.
- Look up sunrise and sunset times.
- Record daily.
- Calculate day length.
- Look for a pattern.
Think about it: what did you notice?
What did you notice? Day length changed slowly.

If a learner struggles
- Find the misconception: “The Sun rises in the west.” East.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain day and night patterns.
- 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 day and night patterns. You do not need to be an expert to help.
- Watch the sunset from home.
- Ask “Which way is west?”
- Do not stare.
- 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 sunrise to sunset; explain time zones simply; compare day and night animals; predict changes in day length.
Prerequisite knowledge. Grade 3 Earth ideas: weather patterns, seasons and shadows.
Materials. Notebook, almanac. 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 times online with adult.
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). Ask, “When is it day in Japan?”
Explanation (10 min). Teach day and night.
Guided activity (10 min). Learners record.
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. East or west? Day or night animal?
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 rises in the west.” East.
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 day and night patterns. 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.
