Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
Aim: To separate the colours from the skittles by using chromatography.
Materials;
1.Skittles
2.Petri Dish
3.Water
Method:
Step 1:Place skittle around the edge of the petri dish.
Step 2:Carefully put water into the middle of the petri dish.
Step 3:Watch to see which colours each the middle first.
Findings:
Explain what happens to the colours? The colour comes off the skittles.
Why do they bleed out at the same rate? they didn't.
Why do the colours not mix together? The colours didn't mix because they have the same amount of sugar.

Green: 4
Yellow: 3
Orange: 4
Brown: 8
Red: 3
