My school actually taught a required computer class in middle school mostly centered around the use of office products. As much as I didn't like the class at the time, it has really proved to be invaluable in things as simple as writing papers, making presentations, budgeting work, analysis of lab data, etc. If you don't have much time, perhaps introduce them to Excel. I still find new functions in it to make my lab work easier every day, and if the kids see the power of such a program, they may no longer disregard it as "boring". Even the more advanced functions of word (center/right align tabs, columns, leaders...) are useful topics.

Other than that, I second a web scavenger hunt, especially for something not so obvious. Good searching skills are becoming increasingly important as the amount of information on the web increases exponentially. Actually, one of the most important skills I see is distinguishing credible sources on the web. Perhaps spend some time on just general web safety (not clicking on unknown advertising links, determining shady sites, checking for ssl/https on payment websites, how much information to give away on the web, etc.). Maybe even have them google themselves and let them see how much of themselves is *already* on the web (and then of course discuss a safe level of information to put out there).

As far as teaching programing/java... I find that kind of a mixed bag. These days, even a very very literate user does not have to touch the actual code of a program. And as much as I love programming stuff myself, I almost always find it easier to find someone who has already solved the problem and shared the program on the web.

Anyways.... that's a really cool opportunity. Most importantly, be sure to make the curriculum fun and have fun with it yourself!
