What You Can Hear Around You
- Your voice, when you say “hello” or laugh, the air moves and makes sound that goes into your ears.
- A toy car zooming, if you push it across the floor, it rumbles like a little engine.
- Music from a radio, it’s like someone is singing or playing a guitar far away, but you can still hear it clearly.
Each of these sounds starts somewhere and travels through the air until it reaches your ears. It's like when you blow on a pinwheel, what you do makes something happen that you can see or feel!
Examples
- A dog barking in the park
- Rain falling on a roof
- A bell ringing at school
