Chromatography-using chemicals to extract pigments

Aim: to extract pigments on the leaves of the trees

Today we did an experiment that uses leaves and pigments.

Equipment:

Boiling tube, Test tube, Pippete, Filter paper, splint, samples, and Ethanol

Method:
1. Get all the materials needed.
2.Put Ethanol in 1 boiling tube
3.put the sample in a test tube
4.Get the pippete and put some ethanol on the other boiling tube
5.Get a filter paper and some splint make a crossed shape that holds the paper so that it won't go to the bottom of the boiling tube
6.mark the filter paper with a pencil about 2 inches
7.Get a pippete and drop some samples on the filter marked filter paper
8.then wait for the pigment to get scattered.

Aim: Our aim is to recreate the experiment using felt pens because it has more concentrated pigments.

Today we recreated our last experiment using felt pens instead of leaves because the pens got more concentrated liquid than the ground leaves

Equipment

Splint
Test tube
Test tube rack
Filter paper
Felt pens

Why the colors are separating?

Because each color have different sizes of particles
