So, you’ve seen the website. You’ve done the online training course. You’ve got the OK to launch this project on your unsuspecting class. You have got your head around 13.8 billion years of history that goes from the minute to the colossal, from bacteria to supernova. You have weighed the balance between science and the humanities and where your strengths and weaknesses will lie.

But now comes the real challenge: How do you tell this epic tale to a class full of fully, barely and partially engaged teenagers whose lives are filled with Instagram, puberty, future goals and nagging parents? The answer? By focusing on the through line and letting everything else take care of itself. Be a whale that comes up for breath, each Big History threshold a mighty spout visible to all, and then dives down again to various depths of the ocean of learning that this course allows.

We all have strengths and weaknesses—as educators, peers, parents, enthusiasts, and humans. We take these aspects into all parts of our lives and work with them every day; the Big History Project is no different. It can be daunting as an history teacher, as I am, to tackle the physics of the Big Bang—nature’s creation event; or the periodic table of the elements and its strange mix of numbers and letters.

While I will never be able to teach my students how ripples in the fabric of gravity have affected the expansion of the Universe, I can always bring them back to the great narrative of the Big History Project: Each stage has created Goldilocks Conditions that have allowed the next threshold of complexity to develop. In this way, my adaptation of the course reflects not just my teaching strengths, but also the aspects of the course that I know will engage and inspire my students. So, like a whale I come up for breath at each threshold and reiterate the point, consolidate the learning and ensure that all my students have grasped the majesty of each stage – stars lighting up, chemical elements exploding to life, our own Solar System being born—all the way to how their old age will look.

Then, when I dive down again into detail, like a whale chasing plankton or simply enjoying the warm waters, I choose with my students the depth of learning and teaching that we will engage in. As a history teacher, it will always have a historical bent; my handful of class periods on the chemical elements zoom in on the wondrous life of Dmitri Mendeleev, using the Life of a Star activity and Mendeleev articles to accompany the Big History video clips. Come Unit 6 and beyond, however, I dig deeper, accessing nearly all the resources from the site and telling the great story of human history and migration. At times it feels rushed and often it feels tangential, but throughout, the through line of Big History is maintained so students can follow the narrative, connect the thresholds, and breathe the narrative of history.

About the author: Garry teaches at Cape Naturaliste College in Vasse, Western Australia. He has taught Big History since 2013. All tenth-year students at his school take Big History. Classes are delivered over the course of a 20-week semester, with four 64-minute class periods per week. Garry says ,“All teachers in our department are BHP aficionados and love the perspective and depth it gives students.”
