Description: 

"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.
Objectives

Big Idea: 

The way a material behaves on the macroscale is affected by its structure on the nanoscale.

Learning goals: 

  • 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.

NISE Net Content Map: 

  • Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.

Universal design: 

  • Repeat and reinforce main ideas and concepts.
  • Provide multiple entry points and multiple ways of engagement
  • Provide physical and sensory access to all aspects of the program. Visitors can touch, see and hear different elements of the program.
