I used this webquest to start my students on my non-fiction unit (the book list is also one of my products). The sections ask: what's the purpose of writing? How is writing a tool? Why do people read? The reflection at the end is question about student motivation.
There are at least four links per section, and you could cut down the number of links as you want. The attached document lists all of the links on the webquest.
Enjoy :) I hope you like it! My kids did!
