SOUND

A unit in which students explore and identify the way sound is made through vibration and find out how the pitch and volume of sounds can be changed.

Using power point presentations, practical activities and worksheets, students

• identify how sounds are made, associating some of them with something vibrating
• recognise that vibrations from sounds travel through a medium to the ear
• find patterns between the pitch of a sound and features of the object that produced it
• find patterns between the volume of a sound and the strength of the vibrations that produced it
• recognise that sounds get fainter as the distance from the sound source increases.

This unit has been used mainly with 8 to 9 year old students.

The activities require some everyday items including some musical instruments for the students to work with.
