Chromatography

Use the scientific technique of chromatography to exchange hidden messages and to create colorful art with the help of water.

In this activity, students work with paper chromatography. This technique separates particles in a water soluble mixture as water spreads through the paper and carries the mixture particles along. Students make use of this property to get water to help them play games and create art. This activity focuses on getting students to experiment with chromatography and try different ideas while creating their art.
