In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

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

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

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

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.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

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

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

This is an activity exploring color and color mixing.
