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

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

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 activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

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 simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

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

This activity teaches combustion as the interaction of a fuel source and oxygen.

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