During our Science lesson this week, we discussed what we knew about light and shadows, then made a class mind map.
We learnt that light seems white but it is really made of 7 different colours (red, orange, yellow, green, blue, indigo and violet). We tested this by making our own spinning wheel, once you spin the colourful wheel very fast, your eyes cannot see the separate colours anymore. They blur together and are seen as “white.”.
First, we had to cut out the two coloured discs and glue them together. Then, we carefully made two small holes and threaded the string though. Once we had assembled our whizzer wheels, we had to practice using them until we were able to keep the disc spinning!
