Looking at an opal through a scanning electron microscope

Colors at the Nanoscale: Butterflies, Beetles and Opals

In this activity, learners will be exposed to the term ‘Photonic Crystals,' explore some of the well-known photonic crystals in nature and will also be able observe one method that scientists use in trying to replicate this process.
Large blue and orange interactive exhibit that features the properties of blue butterfly wings on the nanoscale. Exhibit has three boxes with preserved butterflies under a light and a large sign going into detail on nanostructures

Changing Colors exhibit

An exhibit that was part of the Nanotechnology: What's the Big Deal? exhibition that shows how some high-tech nanomaterials mimic natural phenomena.
Three learners and a facilitator compare their dye colors to a PH scale

Nature of Dye

In this activity, learners create their own dyes and art while exploring how chemicals interact.
Group of learners examine color diffusion on various papers

Chemistry is Colorful

In this activity, learners try to solve the mystery of which ink came from what marker by using colorful paper chromatography.

Exploring Structures - Butterfly

In this activity, learners investigate how butterfly wings get their color and that some wings get their color from the nanoscale structures on the wings instead of pigments.
