This is a lesson plan that centers around a 30-minute activity that gets students thinking and talking about the primary sources they create as they go about their daily lives, in order to prepare them to understand and contextualize the primary sources they encounter in historical research. They will also learn skills that can be transferred to future archival research. This works well as part I of a two-part interaction with classes. Typically, I go to their classroom for this lesson, meeting the students in a room in which they feel comfortable. They then come to the library several weeks later for a research-intensive workshop.
