At the end of this activity, students will be able to explain what a political cartoon source reveals about World War 1 in 1915. They will study the source closely and match events of 1915 from a timeline to particular aspects of the cartoon. By doing this, they will be applying knowledge to use the cartoon as evidence for the war in 1915. They will see that the cartoonist has been selective in what he/she has chosen to include. They will discuss the perspective of the cartoonist on the events of his/her time and how this perspective was shaped. As a plenary activity, they will persuade an author that this political cartoon should be included in a textbook.
