Student lesson
- Sounds can be loud or soft.
- A bigger vibration makes a louder sound.
- Sound is quieter when we are far away.
- Very loud noise can hurt our ears.
Words to know
with a lot of sound
with little sound
how loud or soft a sound is
unwanted or too loud sound
1. Discover: The library and the playground
In the library, Chuka whispers. In the playground, children shout and laugh. A bus passes with a loud horn. “Some sounds are soft and some are loud,” says the librarian. “We choose our volume for the place.”
Think: Why do we whisper in a library?
2. Understand: Volume
Idea 1: Loud and soft
A loud sound is easy to hear. A soft sound is quiet. The volume of a sound is how loud or soft it is. Drums and horns are loud. A whisper is soft.
Idea 2: Changing the volume
A harder hit on a drum makes a bigger vibration and a louder sound. A gentle tap makes a soft sound. Sound is also louder when we are near and softer when we are far.
Idea 3: Noise and ears
Very loud noise can hurt our ears. We keep music low, cover our ears near loud machines and do not shout in someone’s ear.
3. Worked examples
Example 1 (I show you): Loud or soft?
A whisper and a horn.
- A whisper is quiet.
- A horn is loud.
- Compare them.
Answer: A whisper is soft and a horn is loud.
Example 2 (We do it together): Change the volume
A drum.
- Tap gently: soft.
- Hit hard: loud.
- Bigger vibration, louder sound.
Answer: A harder hit makes a louder sound.
Example 3 (You try): Choose the volume
In a library.
Show the steps and answer
- Others are reading.
- We whisper.
- We keep noise low.
Answer: We speak softly in a library.
Did you know?
A blue whale’s call can be heard many kilometres away under water.
Why this matters
Choosing the right volume is kind to others and protects our ears.
4. Explore: Loud and soft
Make loud and soft sounds with a drum or a pot.
- Tap the drum gently.
- Tap it harder.
- Walk away and listen.
- Record which is louder.
Think about it: what did you notice?
What did you notice? A harder tap and a nearer position sound louder.

If a learner struggles
- Find the misconception: “Louder is always better.” Very loud sounds can hurt.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use a drum. Make a soft and loud sound.
- 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 learns about loud and soft sounds and how to protect their ears. You do not need to be an expert to help.
- Talk about quiet and loud places.
- Ask, “Is this safe for your ears?”
- Keep music low.
- 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 sounds as loud or soft; say how to make a sound louder or softer; compare loud and soft sounds; say that very loud sounds can harm ears.
Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.
Materials. A drum, a bell, a pot and spoon, a whistle, 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. Choose gentle sound-makers. Mark distances on the floor. Remind learners about ears.
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 do we whisper?”
Explanation (10 min). Teach loud and soft.
Guided activity (10 min). Learners test volume.
Independent activity (10 min). Learners discuss safe sound.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Is it loud or soft? Is it safe?
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. “Louder is always better.” Very loud sounds can hurt.
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. Use a drum. Make a soft and loud sound. 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.
