  1. The Sun is our main natural light source.
  2. Stars make light.
  3. The Moon only reflects light from the Sun.
  4. Fireflies make their own light.

Words to know

natural
from nature
sunlight
light from the Sun
star
a very far-away Sun in the night sky
firefly
a small insect that makes its own light

1. Discover: The firefly night

One evening, Ope sits outside with her grandfather. The Sun has gone down. The sky has stars. Small lights blink near the bush. “Fireflies,” says her grandfather. “They make their own light.”

Think: Where did the light come from?

2. Understand: Natural light

Idea 1: The Sun and stars

The Sun is our main source of natural light and warmth. Sunlight makes daytime bright. At night we can see stars. Stars make their own light, but are very far away.

Idea 2: The Moon

The Moon does not make light. It looks bright because it reflects light from the Sun, like a mirror.

Idea 3: Living lights

A firefly makes its own light. Some deep-sea fish also make light. Lightning makes a bright flash, but it is dangerous, so we stay indoors in a storm.

Remember: The Sun and stars make natural light. The Moon reflects sunlight. Fireflies make their own light.

3. Worked examples

Example 1 (I show you): Natural light?

The Sun and a lamp.

  1. The Sun is from nature.
  2. A lamp is made by people.
  3. The Sun is natural.

Answer: The Sun is a natural light source.

Example 2 (We do it together): Does the Moon make light?

The Moon at night.

  1. It looks bright.
  2. It reflects sunlight.
  3. It does not make light.

Answer: The Moon only reflects sunlight.

Example 3 (You try): Living light

A firefly.

Show the steps and answer
  1. It blinks.
  2. It makes light.
  3. It is a living light.

Answer: A firefly makes its own light.

Did you know?

The light we see from some stars left them thousands of years ago.

Why this matters

Natural light gives us day, warmth and helps plants grow.

4. Explore: Day light chart

Sort pictures of light sources into natural and made by people.

  1. Collect pictures of light sources.
  2. Sort into natural and made.
  3. Name each one.
  4. Say which are brightest.
Think about it: what did you notice?

What did you notice? Many lights are natural.

Safety first: Never look at the Sun. Do not look at the Moon with binoculars without an adult. Stay indoors in storms. Do not touch fire.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Name natural light sources 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 Sun is our main light source 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 Say that the Moon does not make light 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 Moon makes its own light.” It reflects sunlight.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Use five pictures. Sort natural and made.
  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 about natural light sources like the Sun and stars. You do not need to be an expert to help.

  • Look at the night sky together.
  • Ask, “Does the Moon make light?”
  • Remind your child never to 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: name natural light sources; say that the Sun is our main light source; say that the Moon does not make light; explain day and night with light.

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

Materials. Pictures of light sources, chart paper, glue and crayons. 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. Gather pictures of the Sun, stars, Moon, fireflies and lamps. Draw a two-column chart.

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, “Where does light come from?”

Explanation (10 min). Teach natural light sources.

Guided activity (10 min). Learners sort pictures.

Independent activity (10 min). Learners draw a night sky.

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

Key questions. Is it natural? Does it make its own light?

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 sunlight.

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 five pictures. Sort natural and made. 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.
