Good vibrations


Year 4, what do you know about sound?
Can you explain how sounds are made and how they travel to our ears?

  1. The sound travels through sound waves and vibrations. You can make sounds with instruments and have you noticed that if you hit like a drum or a table with your hands. It will make a sound if you hit it hard it will make a loud sound and if you hit it lightly you will notice that it's level is lower.

    5. It is actually vibrations that vibrate through the air and into your ear. Your brain then processes the sound and sends it to the ear. So he could show you a sound wave by playing an instrument on the table like a cymbal and you could touch it.

  3. If you bang a drum really heard it makes a loud sound and if you bang it lightly it will make a low sound.

    This is how the sound travels to your ear: so you got a Drum stick and then you bang it hard the sound goes to the air the it makes a sound waves and then it goes to your ears and that is how you hear sounds.

  12. sound travel by sound waves into your ear same thing when your friends talk to you. When there is a big hall or cave the sound waves bouse off the walls and makes an eco. When there's a door or some thing it will block the sound from traveling.
