Cutting It Down to Nano

“Cutting it Down” is a cart demo that communicates scale through a hands-on activity. Visitors learn that the nanometer size scale is very, very small—and that we can’t use macroscale tools to manipulate nanoscale materials. During the program, visitors are challenged to cut a small strip of paper in half as many times as they can—or until they reach the nanoscale, which ever comes first.

Surface Area - Cart demo

This is a cart demo about how nanoparticles behave differently, in part because they have a high surface area:volume ratio. Visitors learn that smaller particles have a much higher proportion of their atoms on the surface. Visitors unfold paper cubes, drop alka-seltzer in water, turn potatoes black with iodine, and see fireballs to understand how surface area changes as you get small.

Nanotechnology Part 1: Explore the Nanoscale and Part 2: Nanoproperties

Australian animated videos on nanoscience scale (Part 1) and properties (Part 2). Underpinning an understanding of nanotechnology are two foundational aspects. First appreciating the nanoscale - how might we imagine one billionth of a meter? And second exploring novel nano properties such as conductivity, color and reactivity. This pair of animations explores both scale and properties.

The Scale of the Universe Zoom

This interactive animation is a modern version of the classic powers of ten video. It takes you all the way from the (estimated) outer reaches of the universe down to the length of a Planck. Somewhere in the middle, the animation let's you explore the nano-scale. Click on different objects as they zoom by to learn more.
