In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

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