What Interests High-School Students?

Jim Willis asks: "Our IT Division happens to be populated with some civic-minded people who are interested in making time available for local high-school students interested in science and technology. Question is, we're not sure the best way to do it. We're mulling around the idea of sponsoring a robotics competition or some sort of programming fair/competition. Unfortunately, we've been out of high-school long enough to not know what excites students about technology. Slashdot readers (esp. those of you in high-school): Where should we focus our attention and donate/volunteer our time?"
