As you research, you will want to consider your sources and analyze what they are telling you. Analyzing sources is more than looking at what the sources say. It involves considering who wrote a source, why they wrote that source and its historical context. These questions will help you decide whether your source is reliable or whether it was biased in some way.
As you find sources and analyze them, you will also want to think about how to limit the scope to make your topic manageable. Remember, you only have a small amount of time or space to address your subject, so you want to make sure your topic is narrow enough to be adequately covered in your project. For example, if you are thinking about doing a project on World War II or the Great Depression, you will want to pick a particular aspect of that broad topic to focus on.
