Exploring Properties - Surface Area (NanoDays 08, 09, 10)

NISE Network product
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.

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.
NISE Net Content Map: 
  • Nanometer-sized things are very small, and often behave differently than larger things do.
