Today in Science, the children explored the question, What is sound and how are sounds made? They watched a video about sound and discussed their ideas before carrying out a range of practical investigations. The children explored a variety of musical instruments to discover which parts vibrate to make sounds. They observed visible vibrations by placing items on a drum and watching what happened when the drum was struck with different amounts of force. They also investigated how to make sounds louder and quieter, and how to change the pitch of sounds using different instruments. Finally, the children went outside to listen carefully to environmental sounds, identifying their source, volume and pitch. Through their investigations, the children learnt that sounds are made when objects vibrate and that vibrations can affect the volume and pitch of a sound.
