I first learned about the Khan Academy over a year ago, but was disappointed with the lack of history resources. Over the past year the amount of resources has grown and it continues to grow. The Khan Academy is changing the face of education by providing free educational videos and lessons to anyone anywhere in the world, completely free of charge. The Khan Academy has an extensive library of videos covers K-12 math, science topics such as biology, chemistry, and physics, and even reaches into the humanities with playlists on finance and history. Each video is a ten minute long clip.
