In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

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

In this activity, learners will design a way to identify a powder found at a crime scene by comparing it with known powders, with the goal of solving a crime.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.
