Description

"Buy It, Or Better Not?" explores the many products where we find titanium dioxide (TiO2) in our everyday lives, from chewing gum to sunblock to house paint. In this conversational activity, participants consider the costs, risks, and benefits of nanoparticles in various products, and weigh those against their own values and opinions.

Objectives

Big Idea

Nanoscale titanium dioxide is a common additive found in many products that we consume, rub into our skin, and use in our homes.

Learning Goals
  • Nanoscale titanium dioxide is a common additive found in many products that we consume, rub into our skin, and use in our homes.
  • Materials can act differently when they’re nano-sized.
  • Nanotechnologies have costs, risks, and benefits that affect our lives in ways we cannot always predict.
Nano Content Map
Nanometer-sized things are very small, and often behave differently than larger things do.
Nanotechnologies—and their costs, utility, risks, and benefits—are closely interconnected with society and with our values.
