Before you start any research project, you must decide upon the questions you will be asking.
For example, You have to create a project about the Pyramids. It will require 2 print sources and a web source. Chances are you are not an Egyptologist. At this stage in the process, you don't even know what you don't know. What to do? Go to Wikipedia.
WHAT?!?!? Didn't Mrs. Spilker specifically say NO WIKIPEDIA? Yes, yes she did.
Use Wikipedia to help formulate your questions. Use Wikipedia as a spring board to find primary sources. Just don't use it as a source for your project.
