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 build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this activity, learners investigate the effect of heat on a reaction.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
