Changing Colors is an interactive exhibit that shows how some high-tech nanomaterials mimic natural phenomena. Super-small, light-reflecting structures—instead of pigments—on the wings of some butterflies create intense, iridescent colors. Nanoscientists have replicated this effect with layered, super-thin films. Watch the...

"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact, and how these interactions can have real-world applications. Participants predict, observe, and share what they notice as they experiment with the dye. What's...

Chemistry is Colorful encourages visitors to explore materials through paper chromatography. This process highlights the properties of different pigments blended together in a marker by creating a colorful chromatogram. Can participants solve the mystery of which ink came from which marker? 

"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. Most objects in the universe are so distant from us that we can only...

"Exploring Structures - Butterfly" is a hands-on activity in which visitors investigate how some butterfly wings get their color. They learn that some wings get their color from the nanoscale structures on the wings instead of pigments. "Explore Science -...
