Student lesson
- Percussion instruments are struck.
- String instruments are plucked or bowed.
- Wind instruments use vibrating air.
- Hollow bodies make sounds stronger.
Words to know
instruments that are struck or shaken
instruments with vibrating strings
instruments played by blowing
a strong sound from matching vibration
1. Discover: The bottle band
Kofi fills eight bottles with different levels of water and taps them with a spoon. The fullest bottle gives the lowest note; the emptiest the highest. “We have a xylophone!” he says. His sister blows across the top of an empty bottle and hears a hum. “That one is a wind instrument.”
Think: Why do different water levels change the note?
2. Understand: Instruments
Idea 1: Three families
Percussion (drums, xylophones) are struck. String instruments (guitars, kora) are plucked or bowed. Wind instruments (flutes, trumpets) are blown.
Idea 2: Changing pitch
Shorter strings or air columns give higher notes. Tighter drum skins give higher notes. Players press strings, open holes or tune pegs.
Idea 3: Making sound stronger
Hollow bodies such as a guitar box or drum shell give resonance, making the sound fuller and louder.
3. Worked examples
Example 1 (I show you): Family
Drum.
- Struck.
- Percussion.
- Skin.
Answer: A drum is percussion.
Example 2 (We do it together): Family
Flute.
- Blown.
- Wind.
- Air.
Answer: A flute is a wind instrument.
Example 3 (You try): Pitch
Short pipe.
Show the steps and answer
- Less air.
- Faster.
- Higher.
Answer: A shorter pipe is higher.
Did you know?
The kora is a West African string instrument with 21 strings, played by plucking with both hands.
Why this matters
Understanding instruments lets us make music and appreciate culture.
4. Explore: Bottle xylophone
Build a xylophone of bottles with different water levels and play a tune.
- Line up six bottles.
- Fill to different levels.
- Tap gently with a spoon.
- Order the notes high to low.
Think about it: what did you notice?
What did you notice? Less water gave a higher note.

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
- Find the misconception: “All instruments are struck.” Three families.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain how instruments work.
- 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 builds an instrument. You do not need to be an expert to help.
- Listen to local music.
- Ask “What vibrates?”
- Enjoy making music.
- 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 three instrument families; explain how each makes sound; change pitch on an instrument; build a simple instrument.
Prerequisite knowledge. Grade 3 physical ideas: forces, materials and measuring in fair tests.
Materials. Plastic bottles, spoon. 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 bottles.
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). Play a drum and ask, “What family is it?”
Explanation (10 min). Teach instruments.
Guided activity (10 min). Learners build.
Independent activity (10 min). Learners play.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which family? What vibrates?
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. “All instruments are struck.” Three families.
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 how instruments work. 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.
