colourful experiment

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

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials;
1. cup

2.  you need filter paper or special paper

3. water from sink 

4. the colours you need black green and red

Process:

Step 1: get a cup 

Step 2: get some water
Step 3: get the paper

Step 4: bend the paper a little at the top then put the hook on the edged and it should sit there 

Findings: the colour went up the paper

Reflection: the water can go up paper 

Skittles

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

Materials;

1. Small  Circle containers

2. skittles 

3. water from sink   

Process:

Step 1: spreed out the skittles 

Step 2: pour some water in with the skittles

Step 5: then take out the skittles

Step 6: then you can eat the skittles 

Findings: the colour fared away form the skittle 

Reflection: That skittle colour combined in the middle then we got to eat them    

What did the colours do?
Did the colours mix together?
Why or why not?

Extension:

What is another experiment you could do using chromatography and how would you do it.
