Demonstrate diffusion, density and the particle model to your 14–16 learners in this easy experiment. Download the full instructions and technician notes from Education in Chemistry: https://rsc.li/4d1Au68
Dissolve coloured sweets, such as Skittles, without stirring to create intriguing patterns and make your science lesson or outreach event engaging. The sugar in the sweets can create bulk fluid motion as they dissolve, meaning your learners can see the effects in much shorter time frames than using food colouring and water alone. Try the variations using different temperatures of water to investigate rate of reaction or compare the bands of colour between new sweets and ones you've already dissolved.
