In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

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

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

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

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

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

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.
