Here is a list of helpful websites that will help you in your journey as a Historian:
Kids.Gov - U.S. History site specifically for grades 6-8
Library of Congress - The Library of Congress of the United States. Many great resources and primary documents can be found here
Citation Machine - When you need to give Citations, this site will guide you and help you through it. I will be giving a tutorial on this site in class when projects are given.
WolframAlpha - A fantastic knowledge website/search, not just for history but for science and math as well.
