Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").
