OBJECTIVES

BIG IDEA

A nanometer is a billionth of a meter.

LEARNING GOALS

  • A nanometer is a billionth of a meter.

  • New nanotechnologies include water filters with nano-sized pores and medications that use the human body’s natural filtration system.

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.
