Big History Project
This is big. Really big. The Big History Project is a new online course covering 13.7 billion years of history on Earth. David Christian first started teaching his Big History course in 1989 at Macquarie University in Australia. He wanted to look at history on a big scale, including the disciplines of biology, cosmology, astronomy, geology and anthropology. The class has become so popular, he made this online version of it with the backing of Bill Gates. The site contains all the lesson plans, video, multimedia content and teacher’s guide. It is written for high school and it’s free.
