AC9S2U02 - Sound is made by vibrations
Example 1
: build vocabulary for loudness and pitch and compare sounds.
Example 2
: explore sound-making actions such as striking, blowing, scraping, plucking and shaking.
Example 3
: explore, in culturally appropriate specific contexts, how First Nations musical instruments produce characteristic sounds.
Example 4
: explore the unique sounds of voices.

Questions and answersWith answers
- Sound sources vibrate.
- Actions that can start vibrations include striking, shaking, plucking, blowing and rubbing.
- Loudness = loud/soft.
- Pitch = high/low.
- Change one feature at a time when comparing sounds.
- Materials can muffle sound.
- Echoes are reflected sounds heard again.
Mastery check: Explain what vibrates when you pluck an elastic band and how changing the way you pluck it could change the sound.
Practice and reviewReady for practice
- “Sound appears without movement.” Look, touch safely or observe indirectly; the sound source is vibrating even if the movement is tiny.
- “Loud means high.” Loud/soft is loudness; high/low is pitch.
- “Blowing is the sound.” Blowing starts vibrations in part of the instrument; the vibration produces the sound.
- Changing several features at once. Change one feature so you can tell what caused the difference.
- “The whole instrument vibrates in exactly the same way.” Identify the main sound-producing part where possible.
