Lesson details

Key learning points

  1. Many musical instruments can make different pitched sounds.
  2. Changing the length of the vibrating object can affect the pitch of the sound it produces.
  3. Larger vibrating objects make lower pitched sounds. Smaller vibrating objects make higher pitched sounds.

Keywords

  • Musical instrument - A musical instrument is an object that produces musical sounds.

  • Pitched - How pitched a sound is tells us how high or how low it is.

  • Vibrations - Vibrating is when an object moves very fast from side to side.

  • Affect - When a change occurs between two things, we can observe how one thing affects another.

Common misconception

Children may think that larger and longer objects vibrating produce louder sounds, without linking this to the pitch of sounds.

If working at school, empty the cupboard of as many musical instruments you can find to explore and demonstrate with. Encourage children who play musical instruments to share their experiences too.

Sound meters that detect pitch of sounds, such as Google Science Journal, can be downloaded for free to use on tablets and other electronic devices.
Teacher tip
