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 electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

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

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

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 four-part activity, learners explore how the body works and the chemistry that happens inside living things.

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

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