I am going to do Splash! Fall 2011 at the University of Chicago, where I chose a subject to teach kids. I'm teaching a 1 hour class on the basics on rationality, and I am outlining the topics I want to cover.
Right now, I'm planning on teaching map and territory, reductionism, a basic introduction to biases, and what having a belief should mean (paying rent).
What other ideas would be useful to teach high school students? And does anyone have suggestions on interesting ways to teach these concepts?
Edit: All comments say four is too many topics, I will focus on map and territory and beliefs paying rent.
