Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable
Why are Compact Fluorescent Bulbs More Efficient?
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Exploring the Universe: Filtered Light
"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
Give and Take
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Make a Green Gumball Black
In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!
