Click HERE for a document I created some time ago when being asked to teach a lesson in a social studies context when I got to visit Skot Caldwell's class. I've used it a good deal ever since.
I don't give much detail of how I introduced this investigation -- but we simply started with the text from their own studies. I hope people adapt this lesson for any words they are intersted in. See what you think.
