• Sounds are made when a material vibrates.

• Fast vibrations make a high sound, and slow vibrations make a low sound.

• Large vibrations make a loud sound, and small vibrations make a quieter sound.

• Plucking, blowing, shaking, beating or scraping can make sounds.

• Sound can travel through materials.

• Hard materials can reflect sound so that the sound travels back in the opposite direction. This is called an echo.
