Journey through nearly 14 billion years of history in this self-guided, six-hour version of Big History. Every chapter is full of great activities (videos, readings, quizzes, interviews, timelines). Amazing resource for teaching chemistry, evolution, plate tectonics, genetics, Earth science, etc. in a connected way.

If you do the history of life timeline with students, it would be great to use this web site as a follow-up to answer some of the questions that come up: What is the Big Bang? Did humans evolve from apes? The web site covers a ton of information, but it’s written for high school students, so will be accessible to a lot of our students. If students want one web site to study for the HSE science test, this could be it.
