Examine details in an old photograph to figure out clues about when and how people lived.
A photograph taken long ago is a primary source: a real picture of a real moment, made by someone who was actually there. Unlike a story someone tells from memory, a photo shows exactly what a moment looked like.
Detectives look for clues, and so do historians looking at old photos. Clothing, cars, hairstyles, and signs in the background can all help you guess when a photo was taken.
Mastery looks like: They can look closely at an old photograph and name specific visual clues that show it is from an earlier time.
Common stumbles: Guessing the time period without pointing to a specific visual clue in the photo.
