Sound is a type of energy that we can hear. It travels in waves, kind of like ripples in a pond when you drop a pebble. These sound waves are created by vibrations โ when something moves back and forth really quickly. When these vibrations reach our ears, our ears pick them up, and our brain interprets them as sound! Different sounds have different qualities, like being loud or soft, high or low. Understanding sound energy helps us learn about music, communication, and even how some animals 'see' with sound!
Match the word with its definition:
| Word | Definition |
|---|---|
| 1. Vibration | A. The quality of a sound being high or low. |
| 2. Sound Wave | B. The loudness or softness of a sound. |
| 3. Pitch | C. A disturbance that travels through a medium (like air) carrying energy. |
| 4. Amplitude | D. To move back and forth rapidly. |
| 5. Energy | E. The ability to do work or cause change. |
