| Compressions (areas of high pressure) and rarefactions (areas of low pressure) | Card: 4 / 30 |
| True or False: Sound waves travel faster in gases than in liquids. | Card: 5 / 30 |
| False. Sound waves travel slower in gases than in liquids. | Card: 6 / 30 |
| Fill in the blank: Sound can be described as loud or soft, high-pitched or low-pitched, depending on its ___ and ___. | Card: 7 / 30 |
| Frequency and amplitude | Card: 8 / 30 |
| Riddle: I am created by vibrations, travel in waves, and can be loud or soft. What am I? | Card: 9 / 30 |
| Sound | Card: 10 / 30 |
| What role does the eardrum play in the process of hearing? | Card: 11 / 30 |
| The eardrum vibrates when sound waves reach it, and these vibrations are interpreted by the brain as sound. | Card: 12 / 30 |

| B) They require a medium to travel. | Card: 16 / 30 |
| What causes sound to be created when clapping your hands? | Card: 17 / 30 |
|  The rapid collision of your hands creates vibrations, which generate sound. | Card: 18 / 30 |
| Fill in the blank: Sounds are made by ___, which causes surrounding air to vibrate. | Card: 19 / 30 |
|  Vibrations | Card: 20 / 30 |
| True or False: Sound waves are created when air particles are pushed and pulled, creating areas of compression and rarefaction. | Card: 21 / 30 |
| True | Card: 22 / 30 |
| Riddle: I can be stretched and released, causing vibrations in the air, what am I? | Card: 23 / 30 |
|  An elastic band | Card: 24 / 30 |
| Explain the process that occurs when an elastic band is pulled and released. | Card: 25 / 30 |
| Elastic bands produce sound waves.
| Card: 26 / 30 |
| Fill in the blank: The vibrations in the air particles create ___ that travel to our ears. | Card: 27 / 30 |
| Sound waves | Card: 28 / 30 |
| What is the relationship between vibrations and sound according to the content? | Card: 29 / 30 |
| Vibrations cause the surrounding air to vibrate, and these air vibrations travel as sound waves to our ears, where they are detected as sound. | Card: 30 / 30 |
