Science ~ Chromatography

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. tissue paper

2. felts

3. ruler

4. cup

5. water

6. something to mark it

Process:

Step 1:draw three colors 2 cm away from the bottom.

Step 2:draw a line 3 cm away from the top.

Step 3:then fold it on the line.

Step 4:place in the cup.

Step 5:put water into the cup.

Step 6:wait and see what happens.

Findings: The colors started forming together as the water rises up the tissue paper

Reflection: I have learnt from this experiment that colors can form to be a different colour

Skittles

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

Materials;

1. skittles
2. circle object to hold water in
3. water
4. a lid to close it
5. a camera to record what happens


Process:

Step 1:place skittles evenly apart in the holder.
Step 2:place in the water.
Step 3:record what happens.
Step 4:at the end open the lid.
Step 5:grab a skittle.
Step 6:and eat it.

Findings: the colors of the skittles started melting off to make a rainbow.

Reflection: i have learnt that skittles with water = colorful water 
the colors started melting off of the skittles to make a rainbow
they did not mix together 
they did not mix together because they were evenly spreed out
