You'll probably want to present it in a way that integrates real-life examples. For example, I didn't see the value of functional programming during college, or at least it wasn't emphasized to me in a way which made me interested in it. It's only been the last couple of years in which I realize how valuable it is -- I started looking more into it as I saw companies like Twitter latch onto Scala. So it's probably helpful to give them an idea of what sort of problems computer science is solving in the real world -- whether it's how Google uses MapReduce to process their huge datasets (and what that data is used for) or how integral computer science has been in the field of biology (with fields like bioinformatics). Talking about Facebook and how they use technology is sure to get them interested, or at least, keep their attention
