Scale ladders are diagrams that can quickly convey the size of the nanoscale by showing how objects are related by size. Using existing research on understanding size and scale, the Visualization Laboratory carried out a series of experiments to develop effective scale ladders as well as guidelines for their design and use. This diagram can be dropped as is into an exhibition graphic or used as a template and adapted for different content or graphical contexts.
We've put together resources to help you promote your NanoDays event and other nano educational activities.

"Exploring Products - Nano Fabric" is a hands-on activity exploring how the application of nano-sized whiskers can protect clothing from stains. Visitors investigate the hydrophobic properties of pants made from nano fabric and ordinary fabric.
"Exploring Tools - Special Microscopes" is a hands-on activity in which visitors use a flexible magnet as a model for a scanning probe microscope. They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.
"Exploring Structures - Buckyballs" is a hands-on activity in which visitors fold up a precut shape to make a model of a buckyball. They learn that buckyballs are tiny, soccerball-shaped molecules made of carbon.
"Exploring Size - Measure Yourself" is a hands-on activity in which visitors mark their height on a height chart and discover how tall they are in nanometers. They learn that although being a billion nanometers tall sounds impressive, it doesn't mean they're super tall: it means a nanometer is super small. Visitors can also measure their hands in nanometers.
"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.
"Exploring Materials - Liquid Crystals" is a hands on activity demonstrating that the way a material behaves on the macroscale is affected by its structure on the nanoscale. Visitors investigate the properties of a heat sensitive liquid crystal and make their own liquid crystal sensor to take home.
"Exploring Size - Tiny Ruler" is a hands-on activity investigating just how small a billionth of a meter is. Visitors attempt to cut a paper ruler down to a nanometer-sized sliver. They learn that nano is too small to see, and certainly too small to cut with a pair of scissors!
"Exploring Size - Scented Solutions" is a hands on activity illustrating how small nano is. By sniffing a series of diluted scent solutions, visitors discover that nano-sized particles may be too small to see, but they're not too small to smell!
