Big History ProjectBig History weaves evidence and insights about the Universe (and our place in it) from many scientific and historical disciplines into a unified and coherent narrative. The concept of Big History arose from a desire to go beyond specialized and self-contained fields of study to a deeper understanding of history as a whole. Big History explores how we are connected to everything around us, and where we may be heading. It provides a foundation for thinking about the future and the changes that are reshaping our world. 

To support your middle and high school students at home, veteran BHP teacher Rachel Hansen will guide students daily through the Big History Project on Khan Academy. She will provide content recommendations for each day, along with a Word of the Day and guiding questions. The Khan Academy version of the course also includes a comprehensive set of practice quizzes and activities for students at home.

If you are a parent who wants a little more support as you use these materials with your kids, sign up as a home school teacher at and join the BHP Teacher Community. There you’ll find real-time support from other BHP educators and academics as you support your students, and get answers to your own questions.

Rachel teaches at Muscatine High School in Muscatine, IA — where she and her students like to wear flannels on Fridays and name their class plants. She’s taught the Big History Project for six years and serves as a teacher leader for the program. In addition, Rachel is a National Geographic Explorer whose work focuses on storytelling for impact using podcasts. When not teaching social studies, Rachel enjoys going on outdoor adventures, coaching basketball, and dinking around on the piano.
