"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!
“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.
