Here is a reading on the Smithsonian Institution along with its attendant vocabulary-building and comprehension worksheet. I can’t think of much to say about this: it’s a reading from the Intellectual Devotional series (of which you’ll find a great many on this website) with a basic vocabulary-building and comprehension worksheet (which, like the reading itself, is in Microsoft Word, so you may revise and adapt it for your particular pedagogical circumstances and priorities) I prepared to accompany it.
And that is about it.
