With this activity, you can help your children discover the hidden colors inside the felt-tip pens. In this way, your children design their own paper chromatography to separate colors. Do this activity with your child to learn about chromatography, the process of separating color pigments.
It is a set that introduces the principles of kramotography to students.
Students reproduce multicolored patterns created by an instructor using radial paper chromatography techniques.
What is Chromatography?
Paper chromatography is a method used by chemists to separate the components of a solution. A small amount of sample is taken onto a special paper strip to separate the components of the solution. The end of the paper strip is dipped in a solvent such as water, oil or isopropyl alcohol, and the paper gradually absorbs the solvent. Different color molecules move at different speeds on paper. Color bands form on the chromatographic paper and as a result the solution separates into its components.
