World War I and World War II both had a huge impact on the modern world. Readers explore the history of these wars in a very creative way--through making crafts inspired by these events in American history. Readers learn about different styles of warfare as they make their own periscopes, and they learn about the role the United States played in each conflict as they make their own war posters. These projects are accompanied by enlightening text, including helpful sidebars and fact boxes. Photographs from this period in history engage readers with each turn of the page.
