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

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners explore how musical instruments are engineered.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

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

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 interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

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

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

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 oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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).

Build your own version of the classic physics toy using simple materials.

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.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

This activity is a sensory experience that recreates the sounds of a pond at night.
