Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

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 explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

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".
