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

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

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

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

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.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this activity, learners use simple items to construct a device for indicating air pressure changes.
