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

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 explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this activity, learners become detectives and use chemistry to investigate fingerprints.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.
