In this activity, learners explore how nanosized structures can create brilliant color.

"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.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
