From the most mellifluous notes to the most jarring noises, our ears are often our primary sense-organ and gateway to the outside world. They exist as supremely efficient sound receptors, allowing us to hear things all around us, even if we can’t see them. You can always shut your eyes, but have you ever managed to close your ears without stuffing something inside them? Even then, you will always hear something! Even when you are asleep, and oblivious to most things around you, it is typically a sudden and/or loud sound that will wake you from your slumber. Sound pervades our senses even when we don’t realise it. But what is this something that you hear? Why do things sound so different? Where is the sound coming from? How is it produced? All these questions have intrigued humans since time immemorial, and our understanding of sound today is both deep and accurate.
In this Theme of 3 Open TACtivities, children will explore all the various facets of sound: its fundamental physical characteristics like volume, tone, frequency and speed. We go a bit further and discover that sound acts like a wave. And all this by making a straw/paper 2-reed oboe; a trumpeting bugle using a waste piece of plastic and bottle; and an irritating noise-making device using much the same materials. One of our most treasured and popular themes, this workshop is bound to keep children singing our tune for a long time to come!
