In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

Learn about dyes and mordants (fixatives) when you tie-dye fabric with Kool-Aid™ and vinegar. The colored molecules in Kool-Aid™ form a chemical bond between the fiber and dye molecules.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
