In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

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 how nanotechnology is being used to create new types of protective fabrics.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

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

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.
