Show & tell about the various computer I/O components:

Monitor, Keyboard, Mouse, Scanner, Printer, etc.

Talk about the different levels & types of storage:

Hard-disks, Floppy-disks, CD-ROM, RAM, etc.

Show them a CPU, either get a burned-out one,

or get permission to open the case & show it.

Explain how it controls all the devices through the cards.

If you know anything about programming, show them.

At this point, I would suggest that you ask the class to decide if we should keep making faster PCs to keep up with cheap software, or start back at making better software? What are the pros and cons, and what else could make a difference?

Go the the Intel.com website and they have a lot of good materials to teach this.
