P.4 Colour Wheel Experiment

From this experiment, students learnt that light consists of many colours. They also learnt theories of how colours interact with one another. They were amazed when they spun the colour wheel and it became white.    


'I cut a circle from a cardboard.'

‘Look at our wheel. It's wonderful.'

'Our wheels are fantastic.'

'I'm using a CD to trace a circle on a paper.'

'Let me pass the string through the holes.'

'Use glue to stick the wheels to the both sides of the circled card.'

'Let me show you how to swirl the wheel' 

'Swirl the wheel'

'We cut out two circles from a plain paper.'

'Yeah, we did it.'
