These questions could be written on your board (or projected via website) once a week in secondary history and social studies classes. Students could either answer right away or do a little research through the week (but not on HSP's website, of course) to come up with the answer. Later check out the blog for the answer - and to find back posts of other questions.
What a fun way to learn details of Pennsylvania history and research skills!
Let us know if you try it and how it works!
