I have given talks in both my daughter's and son's classes (when they were in grade 2) on what I do at work. Not on programming per se, but on how an SMS is delivered to a mobile phone (so we also got into programs, databases etc). What struck me the most was the sheer number of questions I got. 4 or 5 hands in the air the whole time when I was answering questions. A lot of smart questions and comments. Very intense and high energy. Contrast that to giving a talk to adults - usually there a lot fewer questions. Overall it was a great experience, and I recommend it if you have the opportunity.
