Chart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts! Nanoscale is the same concept in reverse—can you visualize what 1/1,000,000,000 of a meter would look like? That's the nanometer!
