Colour My World #5: Why is the sky pink?

Light through milky water

Light through clear water

Child initiated inquiry: Why is the sky pink?

When we were playing in the playground one sunny afternoon, Natalya looked up at the sky and asked: "Why is the sky pink?" I told the Water Group about Natalya's question and we researched together. We found an experiment from The Science Book of Color. It shows us how to create a sunset with water, milk, and flashlight which the children eagerly tried it. They exclaimed: "It's orange!" as we shined the light through milky water. We learned that white light from the sun passes through the air. At sunset, only orange and red rays get through the air. Tiny particles of dust or smoke in the air stop all the other colors.

The children concluded the activity by painting their own sunset.
