This Friday I am the "mystery reader" for my son's 4th grade class. As the title suggests, I have about 20 minutes to read basically anything of my choosing. I'd love to hear any age appropriate suggestions that are other than what you might imagine parents choose for something like this. Two ideas I've had so far: Dawkins letter to his 10 year old daughter (already vetoed by the teacher - this one I felt compelled to get prior approval), and one of the dialogs from Godel Escher Bach (maybe Contrafactus?) the "geek-by-association" from which would probably fade by high school in time for him still to be able to date...
Anyway, from those two examples, you get the gist of my nefarious intent. Any ideas? Any of PGs essays work for 10 year olds?
