I would not focus just on programming but on projects. I would get a few Raspberry PIs and some electronic components and let them build and program devices. Build a simple weather lab for temp, humidity, etc. Build a silly traffic light that is triggered by a motion sensor. Have a lamp that can be controlled from a web page. Programming isn't just about web apps and mobile games, so teach them how to build simple projects. Their eyes will open up to all the things computers control all around them. That way they get to decide what they like, hardware, software, both, neither.
