Description

"Exploring Properties - Surface Area" is a hands-on activity demonstrating how a material can act differently when it's nanometer-sized. Visitors compare the reaction rate of an effervescent antacid tablet that is broken in half with one that is broken into many pieces. "Explore Science - Zoom into Nano Ready, Set, Fizz" (2016) version designed for groups and community outreach.

Audience

Objectives

Big Idea

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

Learning Goals

Things on the nanoscale have a lot of surface area, so they react much more easily and quickly than they would if they were larger.

Nano Content Map
Nanometer-sized things are very small, and often behave differently than larger things do.
