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. paper

3. water

4. colored pens

5. 

6. 

Process:

Step 1: Grab a piece of  chromatography.

Step 2: Chose 2 colored felts (light colors)

Step 3:Use a pencil to mark a  line 1cm.

Step 4: Fold chromatography paper and put it in the cup. (make sure it is not touching bottom.

Step 5: wait 

Step 6: Then see as your paper transforms.

Findings: Write about what happened.

Reflection: What have I learnt from this experiment?

Skittles

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

Materials;

1.skittles
2.water
3. petry container
4. 
5. 
6. 

Process:

Step 1: Grab a hand full of skittles.
Step 2: Place skittles in petry container.
Step 3:Place skittles in the outside on inside of container.
Step 4:Add water until it is halfull.
Step 5:Wait until you transform.
Step 6:look as it transform your container.

Findings: Write about what happened.
The water was transformed to beautiful color and then it was like the water ate the skittles.

Reflection: What have I learnt from this experiment?
That the water can transform the skittles if is placed in a circle. 

What did the colours do?Mix/ go to the middle.
Did the colours mix together?yes.
Why or why not?After we mixed it with our fingers.

Extension:

What is another experiment you could do using chromatography and how would you do it.We could it using m and ms to do it another way.
