Through this unit children learn that sounds are produced by vibrations and that these vibrations travel from the source through a variety of materials. Musical instruments are used to illustrate the range of ways of producing sounds and how pitch and loudness can be altered.
Experimental and investigative work focuses on:
- turning ideas into a form that can be investigated and making predictions
- deciding whether the evidence is sufficient to support the prediction.
Work in this unit also offers opportunities for children to use scientific knowledge and understanding about sound to explain familiar phenomena and to relate this to their understanding of musical instruments.
Hearing impaired children will need particular support in this unit. This will be helped by visual demonstrations of the properties of musical instruments and by attention to the vibrations as sounds are produced. It is important for teachers to help children to be sensitive to those who are hearing impaired.
This unit takes approximately 12 hours.
