Exploring Properties - UV Bracelets

In this activity, learners use ultraviolet light to change the color of beads that contain photochromic dye.

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. "Explore Science - Zoom info Nano UV Bracelets" (2016) version designed for groups and community outreach.

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.

NANO CONTENT MAP
