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

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this activity, learners discover that our hands are not reliable thermometers.

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 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.

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 investigate how inkjet printers produce tiny, precise drops of ink.

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

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

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

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).

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

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

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

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

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
