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

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners explore their eye pupils and how they change.

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.

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 are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

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.

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

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".

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