Rainbow Paper

 

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

 

 

This is my end result.

 

Materials:

1. Chromatography Filter Paper

2. Plastic cup

3. Water based felt paper

4. Ruler

5. Pencil for marking

 

Process:

Step 1:  Firstly we selected a group containing 3 member suitable for this experiment.

We then had to get a Chromatography Filter Paper, Ruler, Water based felt pen and a Pencil

Step 2:  Secondly, On the Chromatography Filter paper we had to rule a line from the bottom of the paper 1 cm going up.

Step 3:  After that we had to put 2 dots on the pencil marking, my group and I we used Green and Purple coloured Water Based Felt Paper.

Step 4: Then we had to get a clear plastic cup and place the piece of Chromatography Filter Paper, with the paper the side that has the markings and dots has to face downwards or into the bottom of the plastic cup, but the rest of the paper hanging out of the Plastic Cup you can gently fold that on the outside of the Plastic Cup.

Step 5: After that we have to give or show one of the teachers our Plastic cups with our Chromatography paper and then the teacher will pour a small amount of water into your Plastic Cup.

Step 6: Finally, after the water is inside the Plastic Cup, then you will see a change of colours showing up on the Chromatography Filter Paper, On our paper we noticed that we’ve made two different colours which were Pink and Blue, also we noticed that the colours have traveled.

Conclusion: What have I learnt from this experiment?

Today I learnt that there are more than one colour in the felts. The end result looks so cool and I enjoy it heaps. From this I think that science is starting to interest me. I hope to do this again thank you and bye.
