This tool shows the working of a computer CPU using the Little Man Computer Model (LMC).
The Little Man Computer was created by Dr. Stuart Madnick of MIT as a model for teaching the workings of a CPU. The LMC models the working of a modern CPU, but is still simple enough to be understood and programmed by high school students.

This module uses a combination of discussion and participant involvement to learn about the differences between analog and binary representations of information. Since computers use a binary numbering system, participants learn how to count in binary.
The goal of this activity is to illustrate the basics of working with the binary numbering system.

The goal of this module is to conceptualize how communication happens between the parts of a computer. Placed into the context of the things we use the computer (typing, displaying characters on the monitor, accessing the Internet) we can gain a clearer understanding of how the parts work together to accomplish tasks. Understanding this process is useful when troubleshooting hardware or software problems.

This site has lots of free PowerPoint slides for teaching. This link points to the page with links to technology presentations. Many of the computer presentations are excellent!
I really like this set of slides on how computers work.

Interesting way of looking at how large a petabyte is.
Here are some good computer science lessons for K-12:
I thought this was a very good demonstration of sorting by a cute little girl!
A product of Queen Mary, University of London, this looks very interesting! The site describes itself like this.
“Explore how computer science is also about people, solving puzzles, creativity, changing the future and, most of all, having fun.”
The cs4fn magic book looks particularly good.
There is an applet where you can do some simple AI programming for a game of Noughts and Crosses ( Tic-Tac-Toe ).
Another good applet is the What is an Algorithm applet.
