Digging For Answers is an activity from the Smithsonian Institution. Users can pick choose one of the museum’s collections, and are then asked a series of related questions. If you pick the wrong one, you’re given the url address of a site where you can find the correct one.
It’s probably accessible to High Intermediate or Advanced English Language Learners.
I’ve placed the link on my U.S. History page.
…pick or choose, or both?-) Twittering must be getting at you…-)
