A learning module with built-in interactive features where students can observe how electrons behave. Using a virtual scanning tunneling microscope (STM), they experiment with moving the electrons inside an atom around. The STM has two...

In this comprehensive interactive tutorial you will learn about the parts of a microscope and how some types of microscopes are better than others for certain types of evidence analysis within the field of Forensic Science. A...

How do we see things too small to be detected by the human eye? What about things inside our own bodies? Dee Breger uses a scanning electron microscope to give us a glimpse of images including blood clots, thyroid glands, and lungs with...

Use a virtual scanning tunneling microscope (STM) to observe electron behavior in an atomic-scale world. Walk through the principles of this technology step-by-step.

A learning module that investigates a powerful tool to observe and manipulate atoms called the scanning tunneling microscope.
