NASA, one of my favorite sources for great, free, quality science resources, has a Virtual Field Trip of their Jet Propulsion Lab (JPL).
The student picks an avatar, and then Curtis, the virtual tour guide, shows the student around the JPL, explaining what the mission is and what they do. There are links to NASA mission web sites and much more.
It's a fun, creative way to learn more about NASA, the JPL, and science.
