Looking Around 2 — About Me / Games We Play. Everyday sounds we hear while playing and talking connect with the "About Me" senses topics.
What you'll learn
- Sounds can be loud or soft.
- Hitting, blowing, or plucking harder makes a sound louder.
- Loud sounds can hurt our ears if we stay too close for too long.
Key concepts
Verbal: A loud sound is big and strong, like a drum beaten hard or a train horn. A soft sound is small and gentle, like a whisper or a ticking clock.
Symbolic: Hit/blow harder -> sound gets louder. Hit/blow gently -> sound stays soft.
Level 1 — Loud sounds
A big drum beaten hard, a bursting balloon, a train horn, and thunder are all loud.
Level 1 — Soft sounds
A whisper, a ticking clock, rustling leaves, and a purring cat are all soft.
Level 2 — Changing loudness
The same drum can be loud (hit hard) or soft (tapped gently) — loudness depends on how hard we hit it.
Level 2 — India
The loud sound of firecrackers on Diwali versus the soft sound of a temple bell rung gently.
Worked example
Why does a drum sound louder when you hit it harder?
Step 1 — Hitting harder makes the drum skin vibrate more.
Step 2 — Bigger vibrations carry more sound energy.
Step 3 — More sound energy reaches our ears as a louder sound.
Answer: A harder hit makes a louder sound.
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| All sounds are the same loudness | Ignoring how hard you hit or blow | Harder action -> louder sound |
| Loud sounds never hurt | Ears feel pain from very loud sounds | Cover ears near very loud sounds |
| Soft sounds cannot be heard at all | Soft just means gentle, not silent | Soft sounds are heard up close |
