Chromatography

Skittles

Aim: To separate colours by using the process of chromatography.

Materials;

1. Petrie dish
2. Liquid
3. 5 Skittles 

Process:

Step 1: Get a Petrie dish or a plate
Step 2: Put your 5 skittles in the Petrie dish
Step 3: Put a little amount of water, just a little bit.
Step 4: Watch the water turn to a rainbow colour.
Step 5: Time to eat your skittle
Findings: 

So what happens is when you put a skittle or mm in the water, their colour is going to wash away because they're just a food colouring

Reflection: What have I learned from this experiment?

I learned that when you put mm or skittle in the water there colour will start to disappear
What did the colours do? It disappeared 


Did the colours mix together? Not at the start but when it was like 1 minute, it started to mixed.
