Observe what happens. The process of chromatography is used to separate things in a mixture. In this experiment, the colors move up the paper at different rates because they mix unevenly with water. Most colors are made up of other colors. You will probably be surprised to see the different colors that make up the original color.
Scientists use chromatography to separate different chemicals.
More Challenges Repeat the experiment using different colors of markers, different brands of markers, permanent markers and different temperatures of water. Create a chromatography picture. Take a whole coffee filter and decorate it with colored dots. Fold the co ffee filter in half and put the edge in a pan of water. Watch what happens.
