Year 6 continue their work on refraction

This week, year 6 have continued their work on refraction. Exploring how ‘white light’ is actually made up of a spectrum of colours.

We used water in a glass to refract light; creating a rainbow like image mostly consisting of: red, orange and blue.

Fun was had blowing bubbles to see how the light refracted when it hit the bubble mixture. All seven colours of the spectrum were spotted within the bubbles.

Our final activity started with the seven colours of the spectrum on a disk, we then tried spinning these (really quickly) until the colours appeared white. A few members of year 6 made some great colour spinners- and achieved the desired effect. However this task was really tricky. Can anyone make a better colour spinner at home? What adaptations could you make to get the spinner to spin quicker?
