How Physicists Make Color
Saturdays, July 2–September 3
1:00–2:00 p.m. in the McBean Theater
In this lively presentation, Ron Hipschman, Exploratorium staff physicist, will talk about many ways to make color—from neon signs to oil slicks to rainbows. You’ll learn all about light, how it’s made, and how it interacts. Ron will demonstrate many of the concepts, and you’ll take away materials that will allow you build your own spectroscope (an instrument that separates light into its component wavelengths). You’ll see color in a whole new light! Free with museum admission.
The Color of Maya Cosmology
Sunday, July 3, and Saturday, August 13
2:00 & 3:00 p.m. in the skylight area
Meet Exploratorium astronomer Dr. Isabel Hawkins and Maya Elder Maria Avila Vera and her family from Merida, Yucatán. Isabel and Maria will describe the relationship between color and the Maya view of the cosmos. Learn the Maya names for the cardinal directions and their associated colors and meanings, and why the color red has held special significance for thousands of years. Find out how the movements of the sun, the cycle of corn, and the Maya calendar are related and form the basis of the Maya worldview. You’ll also have a chance to ask these Maya cultural experts about their perspectives on the end of the Maya calendar and the year 2012. Free with museum admission. The Color of Maya Cosmology will be presented in Spanish upon request.
Pigments and Paints
Saturdays, July 16 & 23*, August 6 & 13, September 3
*1:00–4:00 p.m. on July 23

Meander through an open-air market of colorful wares made by local artisans and meet with artists, dyers, chemists, and other color connoisseurs to experience some practical—and aesthetically pleasing—applications of the visible spectrum. You can also try a rainbow of hands-on science activities. CALL FOR LOCAL ARTISTS: We invite you to participate!
Iron Science Teacher
Live webcast on June 25
Cheer on the competitors in this zany science cook-off, where teachers compete before a live audience in the Exploratorium webcast studio. Parodying the cult Japanese TV program “Iron Chef,” the Iron Science Teacher competition showcases science teachers as they devise activities using a “secret” ingredient—in this case, color. Iron Science Teacher activities are designed for the classroom, but many can be done at home as well. Watch on the Exploratorium TV website.
