Develop a Thesis Statement: NHD projects should do more than just tell a story. Every exhibit, performance, documentary, paper and web site should make a point about its topic. To do this, you must develop your own argument of the historical impact of the person, event, pattern or idea you are studying. The point you make is called a thesis statement. A thesis statement is not the same as a topic. Your thesis statement explains what you believe to be the impact and significance of your topic in history.
