Room 9 enjoyed taking part in a science activity today. The only materials they used were a glass of water, piece of paper and a light source. Using the sunlight and torches, the students were able to make their own rainbows. Rainbows are caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky.
We gained excellent results using the sun as a light source. Colours of the rainbow were created when the light source travelled through the glass of water, refracting the beam of light causing it to separate into the colours.
Why don't you have a go yourself at home.
