Imagine a group of kids working together on a retrospective of the Civil War. One student is at the public library, going through microfilm of newspaper articles from 1861 to 1865. She finds a reference to the political ramifications of a certain battle-notably, a picture of an influential officer. The student then uses her smartphone to snap a picture of the microfilm screen and sends the picture and caption to her group for additional research.
