The "Primary SPACE Project Research Report: Sound" (Watt and Russell, 1990) provides interesting reading relating to primary-aged children's concepts of sound. It reveals a range of children's views on how sound is made, how sounds are heard and how sound travels. While some children are shown to have knowledge that sounds travel and are the result of something vibrating, others clearly have misconceptions. So, how best to teach the concept of sound? Perhaps by allowing children to explore creatively a set of everyday objects that produce sound. This allows deductions and understanding from everyday observation and exploration. If children make their own 'instruments," and sounds with everyday objects, they will be able to explore ways of changing the timbre, pitch and volume. The authors present three sessions in creative physics that have been used, over the years, with a variety of classes of children.
