I usually use this activity as an introduction to my U.S. industrialization unit. In this activity, students play the role of detectives, as they will examine a variety of primary sources from political cartoons, graphs, charts, images, etc, to predict what they think happens during the Industrial Era. They will make a prediction for each primary source on the sheet provided. Each source directly corresponds with one effect of the Industrial Era on U.S. society. Students will then write a short paragraph where they use clues from the primary sources to make a logical conclusion about what happens during the Industrial Era. The answer key is provided for your use.
