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

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

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

Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

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.
