Exploring Materials - Ferrofluid

In this activity, learners investigate the properties of ferrofluid and magnetic black sand, learning that the surprising difference in the behavior of these two materials is due to size.

DESCRIPTION

"Exploring Materials - Ferrofluid" is a hands-on activity demonstrating that a material can act differently when it's nanometer-sized. Visitors investigate the properties of ferrofluid and magnetic black sand, learning that the surprising difference in the behavior of these two materials is due to size.

OBJECTIVES

BIG IDEA

A material can act differently when it's nanometer-sized.

LEARNING GOALS

  • A material can act differently when it’s nanometer-sized.

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.
