Mysteries of the Unseen World Education

Discover Things Too Slow, Too Fast, or Too Small to See

Copyright 2013 National Geographic Entertainment

Existing and emerging technologies are giving science exciting new images of long-hidden worlds—allowing viewers to see things not visible to the naked eye. Using high-speed and time-lapse photography, electron microscopy, and nanotechnology, one can peer into these invisible realms of things too fast, too slow, and too small to see. 

This collection of selected videos, activities, microscopic images, articles, and other resources was created to accompany National Geographic Entertainment’s Mysteries of the Unseen World 3D film. You are invited to use these resources to help students describe the relationship between light and visibility, examine the properties of objects at the nanoscale, explore advances in nanoscience and nanotechnology, and journey into the unseen world around us.
