The science activity is called Seeing Sound.
It is based on a branch of science/art called Cymatics.
‘Cymatics‘ It is derived from the Greek ‘kyma’ meaning wave.
In these experiments we made slime and then made the slime dance using a vibrating loudspeaker controlled using iPads.
We also made geometrical sand art using a device called a “Chladni Plate‘.
First the child sprinkles some coloured sand on the Chladni Plate.
Using an iPad, a child selects various images (boomerangs, butterflies, stars) and a representation of that image appears on the vibrating plate along with corresponding sounds.
The beauty of Seeing Sound is the fact that it connects music, shape, and images with physical movement (i.e vibration).
