To do on your own: Open sample source 1 and skim just a bit of it/scroll through to notice sections and characteristics. - you won't be able to read the whole thing, but you can get an idea of what the source is about, and think about what evidence the author used. Use Google if you need help finding out more about the article. Notice the structure of the article and any characteristics about the article that you want to discuss with the class.
Think about this question:
What kind of article is this and what clues helped you figure this out?
