When I first began homeschooling I never really considered Geography a subject. I mean, that is part of History right? Oh, I was so wrong! You see, I could barely follow a map. I knew little to nothing about our world, the state capitols of the United States or the different countries located within the seven continents. Why? Because I was never taught Geography.

National Geographic is a huge website! It would take a person a long time to go through the whole thing. Take the time to teach your student how to use this website. It is well worth your time, especially for the photographs. For instance, search on volcanoes. This is a wonderful website for for unit studies and research projects.
