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 chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

Heat makes some materials expand, and it makes others shrink.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

No glue is needed for learners of any age to become marshmallow architects or engineers.

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

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
