Aim: To separate colours by using the process of chromatography.
Definition: A technique for separating the different parts of a mixture / solid using liquid.
Name of experiment: Rainbow paper
Materials:
1. Chromatography paper
2. A cup
3. Green felt pen
4. Red felt pen
5. Black felt pen
6. Ruler
7. Water
Process:
Step 1: Get your Chromatography paper and draw 1, 2 cm line near on end of the paper.
Step 2: On the other end draw a 1 cm line
Step 3: On the 1 cm line draw a black dot, a green dot and a red dot. Make sure they're not too big/little.
Here is an example: (You can barley see the 2cm line the next step will tell you why).
Step 4: Fold the 2 cm line
Step 5: Get your cup and fill it with water
Step 6: Next put your piece of paper in the cup.
Make sure the water JUST reaches the dots.
Findings: I found out that the colours move quite quickly at first but slow down afterwards. You have to be patient and careful for this experiment.
Reflection: What have I learnt from this experiment? I learnt that Chromatography is a thing! I had never heard of it before, and learning about it was pretty cool.
Awesome post Shreya and I love how you included some of your own pictures to go with it. It sounds like you enjoyed this experiment and learned a little bit about chromatography! Keep up the great work.
