"Exploring Properties - UV Bracelets" is a hands-on activity in which visitors use ultraviolet light to change the color of beads that contain photochromic dye. They learn that the UV beads change color as a result of nanoscale shifts in the shape of the dye molecules.
- The way a material behaves on the macroscale is affected by its structure on the nanoscale.
- The UV beads in this activity change color as a result of nanoscale shifts in the shape of their molecules.
- Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
