Few high school or college students get the chance to use an electron microscope, but they can operate a virtual one at this site from the University of Nijmegen in the Netherlands. The simulator mimics controls on a field-emission scanning electron microscope, allowing users to zoom in on flea's stabbing mouthparts, for example, and probe the anatomy of a leaf's surface.

The microscope activities anchor chapters that explore the plumbing system of plants, flower development, the structure and growth of hair, and other topics. These images of a cutaway leaf show a chain of chloroplasts and a close-up of one light-gathering organelle. Teachers will find a gallery crammed with more than 500 photos, animations, and video clips—from cross sections of a rat's intestine to footage of a fish louse munching a carp's skin.
