Colour My World #3 - What is colour?


This week we explored one of Enxin's inquiries: How come there is colour? What is colour?

To help the children understand that we see colours through light, we did an experiment. First we sat in the dark and the children immediately noticed that they couldn't see anything. Then I asked the children to grab a piece of fabric from the dark and shone the flashlight on it. They each exclaimed the colour in his/her hands. 

They came to the conclusion that we cannot see anything in the dark (not even colours) and when there is light, we can see. 

I explained to the children that all light rays contain colour. When light shines on an object, only some colours bounce off it. Our eyes detect the colours in the light coming from objects and we see them as that particular colour.
