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 make a paper model of a polymer, then make Silly Putty, an actual polymer.

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

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

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.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

This activity teaches combustion as the interaction of a fuel source and oxygen.
