Skittle Colour Experiment
Aim
I want to find out what happens when you mix Skittle colours.
Method
Equipment
- Skittles
- Petri disk
- Warm water
- Beaker
- White background
Instructions
- Get your equipment
- Place your petri dish on the white background
- Put your Skittles around the edge inside the petri dish
- Pour warm water into the middle of the petri dish, gently.
- Observe what happens.
Prediction:
I think the colours from the Skittles with slowly blend into the middle, all the Skittles will lose their colour and turn white.
Results
The Skittle's colour fell of the Skittle and when into the water go into the middle.After a little the colours merged.
Discussion
1. The colours dissolved (when a solid is mixed into a liquid, creating a solution).
Why did the colours spread?
2. Once the colours dissolved into the liquid, the high concentration of colour moved into the middle where the there a low concentration of colour. This is called diffusion.
