This week in Science Club, we explored the primary chemical principle of diffusion—the movement of particles from an area of higher concentration to an area of lower concentration.
When Skittles are placed in water, the sugar and food coloring dissolve and spread out, creating a colorful display as the colors move through the water.
We then posed further questions to investigate:
- Will the temperature of the water affect the rate of diffusion?
- Will changing the type of liquid make a difference?
These questions help us think about how factors like temperature and solvent properties influence diffusion.
‘I believe that diffusion is when the concentration of sugar in the skittles has lost some colour into the water and it started making a colourful plate’

‘The reason why the skittles made colourful swirls is because the water was warm and warm water has energy so it moves faster but if you use cold water it would take longer than warm water because warm water has energy.’
