Words to know

Earth
the planet we live on
spin
to turn around
sunrise
when the Sun first appears in the morning
sunset
when the Sun goes down in the evening

1. Discover: Sunrise and sunset

Early in the morning, Idris sees the Sun rise over the hills. At the end of the day, it sets in the other direction and the sky turns orange. “Why does the Sun go away?” he asks. His teacher says, “The Earth turns, so the Sun seems to move.”

Think: Why does the Sun seem to move?

2. Understand: Day and night

Idea 1: The spinning Earth

The Earth is a huge round planet. It spins once every day. We do not feel it moving because everything on it moves together.

Idea 2: Day and night

When our side of the Earth faces the Sun, it is day. When it turns away, it is night. Sunrise is when the Sun first appears. Sunset is when it goes down.

Idea 3: Our days

In the day we go to school, play and work. At night we sleep, and the body rests. People on the other side of the world have day when we have night.

Remember: The Earth spins. When our side faces the Sun it is day; when it faces away it is night.

3. Worked examples

Example 1 (I show you): Why is it night?

Our side faces away from the Sun.

  1. The Earth has turned.
  2. The Sun cannot light us.
  3. So it is night.

Answer: It is night because our side faces away from the Sun.

Example 2 (We do it together): Order

Sunrise, noon, sunset.

  1. Morning sunrise.
  2. Middle of the day noon.
  3. Evening sunset.

Answer: Sunrise, noon, sunset.

Example 3 (You try): Model

A ball and a torch.

Show the steps and answer
  1. Torch is the Sun.
  2. Ball is the Earth.
  3. Turn the ball.

Answer: Turning the ball shows day and night.

Did you know?

Because the Earth spins, people in different places have day and night at different times.

Why this matters

Day and night give us a rhythm for work, rest, play and sleep.

4. Explore: Day and night model

Use a torch and a ball to show day and night.

  1. An adult holds a torch.
  2. Hold a ball with a mark for your home.
  3. Turn the ball slowly.
  4. Say when your mark has day or night.
Think about it: what did you notice?

What did you notice? Turning moves us in and out of the light.

Safety first: Do not shine the torch in eyes. Never look at the Sun. Move carefully in the dark room.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Explain day and night in simple words 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 Say that the Earth spins 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 Show day and night with a model 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

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

  1. Find the misconception: “The Sun goes around us.” The Earth spins.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Use a ball and torch. Show day and night.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child learns why we have day and night. You do not need to be an expert to help.

  • Watch sunrise or sunset safely.
  • Ask, “Why does the Sun set?”
  • Use a ball and lamp to show it.
  • 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: explain day and night in simple words; say that the Earth spins; show day and night with a model; describe what we do in the day and at night.

Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.

Materials. A torch, a ball, tape, a dark room and chart 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. Mark a point on the ball. Darken the room carefully. Test the torch.

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, “Why does the Sun go away?”

Explanation (10 min). Teach the Earth’s spin.

Guided activity (10 min). Learners model day and night.

Independent activity (10 min). Learners draw their day.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. Is our side facing the Sun?

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 us.” The Earth spins.

13–15. Assessment questions, answer keys, marking scheme

Use the quiz, the 11-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. Use a ball and torch. Show day and night. 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.
