Exploring Materials - Polarizers

  • polarizers and transparent tape
NISE Network product
Description
"Exploring Materials - Polarizers" is a hands-on activity in which visitors use two polarizing sheets and overlapping layers of transparent tape to see how polarizers affect light. They learn that researchers are using nanotechnology to improve existing materials, in this case polarizing filters.

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.

Nanotechnology takes advantage of special properties at the nanoscale to improve existing materials.

Nano Content Map
Nanometer-sized things are very small, and often behave differently than larger things do.
Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
