In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
