How to make a rainbow
Children love to learn and experiment with new things. Try this simple science experiments that is fun to do and will teach your children about refraction of light.
• Glass of water
• White paper
• Direct sunlight
Take a glass of water and paper to a part of the room where there is a window and direct sunlight.
Hold the glass of water above the paper and watch as sunlight passes through the glass of water and forms a rainbow of colours on your sheet of paper.
You can move the paper around a little to see different reflections.
• Rainbows occur when sunlight refracts (bends) as it passes through water. The sunlight refracts, separating it into the colours red, orange, yellow, green, blue, indigo and violet.
• This is why you can often see a rainbow after a rain shower - the sunlight is refracted through raindrops to create a rainbow in the sky.
