Selecting a topic can be the most important and most difficult step of your research project. An ideal topic:
Research is the process of finding answers to questions. If your topic is simply a word or phrase ("microaggressions" or "sustainability"), you're not ready to research. First, you need to turn your topic into a research question.
What do you want to know about your topic? What questions do you have or do you think your audience will have?
Use journalistic questions (Who, What, When, Why, Where, and How) to get started.
If you're feeling stuck for a good idea, start with one of these resources. Simply browse around until a topic catches your attention!
Other brainstorming sources include the news, Wikipedia, your friends, and magazines - a topic is only ever as good as the work you put into researching it.
