= = =Virtual SEM =

Microscopes have come a long way since the days of Leeuwenhoek. The scanning electron microscope (SEM) makes it possible to see details he couldn't imagine. In this Planet Diary activity, you'll peer through a virtual SEM to explore the micro-world. Directions
 * Go to [|Virtual Scanning Electron Microscopy] from Molecular Expressions. Select //Carpet Beetle// from the //Choose a Sample// menu. Slowly slide the focus bar until the image looks sharp. Adjust the contrast and brightness bars for the best view.
 * Slide the Magnification bar to its lowest power (60x for the beetle). Slowly increase the magnification and notice the details. How would you describe the structures you see? Record your observations in the SEM Journal in the Workspace.
 * Explore the other specimens listed on the table to complete your journal.
