Exploring Products - Sunblock (NanoDays 2011 and 2012)

  • Exploring Products - Sunblock
NISE Network product

"Exploring Products - Sunblock" is a hands-on activity comparing sunblock containing nanoparticles to ointment. Visitors learn how some sunblocks that rub in clear contain nanoparticles that block harmful rays from the sun. "Explore Science - Zoom info Nano Invisible Sunblock" (2016) version designed for groups and community outreach.



Big Idea

Sunblocks containing nanoparticles are one of the most common applications of nanotechnology

Learning Goals

Sunblocks containing nanoparticles are one of the most common applications of nanotechnology

Nanoparticles in sunblock are invisible to the human eye because they're smaller than the wavelength of visible light.

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.
Nanotechnologies—and their costs, utility, risks, and benefits—are closely interconnected with society and with our values.
