Really just an excuse for me to post a favorite shot from Brooks Falls, Katmai, Alaska a few years ago. Arctic Lynx.
In any case, I always found some utility in big pages of links for video series. Links to videos (where possible) and question sets. So I made some for video series in various content areas. Here's what I've got.
My first course in physics was Project Physics, Harvard's post-Sputnik curriculum project that emphasized the history of physics and human interest throughout the course. I loved Project Physics. And on Sunday, September 28, 1980, Carl Sagan's Cosmos: A Personal Voyage episode 1, "The Shores of the Cosmic Ocean" aired for the first time. Cosmos grabbed me and did not let go.
I eventually became a high school physics teacher (the only career choice I specifically eliminated from my constellation of options while still in high school). And when California's state-mandated physics testing and reporting ended in the 2010s, I decided to weave Cosmos into my physics curriculum.
By then, I had been implementing Skepticism in the Classroom, stand-alone lessons that could be dropped into the physics curriculum where appropriate. One theme of Cosmos was skepticism, so it aligned with my agenda. I wrote up question sets for each episode, and showed one episode the day after each unit test. I had to up the pace at the end of the year, and I showed episode 13, "Who Speak for Earth?" without a question set. Students were ready by then and remained engaged; it was like lifting hands off the moving bicycle's handlebars.
When Cosmos: A Spacetime Odyssey debuted in 2014, I added that series to my AP Physics 2 curriculum. AP Physics 1 got no Cosmos. But they did learn about waves and circuits back in those days.
In 1980's Cosmos, an existential threat that Sagan was overtly warning about was the nuclear arms race and the possibility of a life on Earth-ending nuclear war. In 2014's Cosmos, an existential threat that Ann Druyan (through Neil deGrasse Tyson) warned about was anthropogenic climate change.
The first episode of Cosmos: Possible Worlds aired on March 9, 2020. Four days later, I taught the last regular, in-person class of my 35-year high school teaching career. Druyan's third season of Cosmos got lost in the pandemic. And National Geographic made the series difficult to find and watch (especially for those dozen or two of us that don't subscribe to cable or have a dish).
Developing question sets for each episode of Possible Worlds has been on my to-do list since 2020. Forty-two years after the debut of Cosmos, I have begun my work on Possible Worlds.
All seasons of Cosmos bring context and humanity to the work done in science. I think it's a valuable resource to fold into course curriculum. It is not tightly-focused content exposition, as one might find in The Mechanical Universe. But that's a feature, not a bug.
One down; 12 to go before I have a full set for Possible Worlds (Cosmos season 3). In the meantime, question sets for seasons 1 and 2 are available at The Lessons of Phyz.
National Geographic · 2014 · Presenter: Neil deGrasse Tyson
Cosmos: A Spacetime Odyssey, is a thirteen-part American science documentary television series released in 2014. The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan is considered a milestone for scientific documentaries. This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films. The show is presented by astrophysicist Neil deGrasse Tyson, who, as a young high school student, was inspired by Sagan.
1. STANDING UP IN THE MILKY WAY Tyson opens the episode to reflect on the importance of Sagan's original Cosmos, and the goals of this series. He introduces the viewer to the "Ship of the Imagination", the show's narrative device to explore the universe's past, present, and future. Tyson takes the viewer to show where Earth sits in the scope of the known universe, defining the Earth's "address" within the Virgo Supercluster. Tyson explains how humanity has not always seen the universe in this manner, and describes the hardships and persecution of Renaissance Italian Giordano Bruno in challenging the prevailing geocentric model held by the Catholic Church. To show Bruno's vision of the cosmic order he uses an animated adaptation of the Flammarion engraving, a 19th century illustration that has now become a common meme for the revealing of the mysteries of the Universe.
The episode continues onto the scope of time, using the concept of the Cosmic Calendar as used in the original series to provide a metaphor for this scale. The narration describes how if the Big Bang occurred on January 1, all of humankind's recorded history would be compressed into the last few seconds of the last minute on December 31. Tyson concludes the episode by recounting how Sagan inspired him as a student as well as his other contributions to the scientific community.
Cosmos: A Personal Voyage is a thirteen-part television series that covers a wide range of scientific subjects, including the origin of life and a perspective of our place in the universe.
I turned 16 while this series aired, and was completely captivated by it. My father had been a fan of Bronowski's Ascent of Man and Burke's Connections. Those were outstanding series in their own rights. But I was all about astronomy, and Sagan's journey resonated with me.
Sagan's Cosmos aged very well and is still regarded as among the best science miniseries ever produced. And as WIRED noted, Sagan's still right all these years later.
The way I used Cosmos was as a "chill day" between units in Physics. For my students, and for me. We all needed it. I kept their question sets after each episode. At the end of the year, I'd give them their sets back and they could use them on a "Cosmos Unit Test". Easy with the completed question sets; challenging without. Definitely among my longest "delayed gratification" activities.
1. THE SHORES OF THE COSMIC OCEAN Carl Sagan opens the program with a description of the cosmos and a "Ship of the Imagination" (shaped like a dandelion seed). The ship journeys through the universe's hundred billion galaxies, the Local Group, the Andromeda Galaxy, the Milky Way, the Orion Nebula, our Solar System, and finally the planet Earth. Eratosthenes' successful calculation of the circumference of Earth leads to a description of the ancient Library of Alexandria. Finally, the "Ages of Science" are described, before pulling back to the full span of the Cosmic Calendar. Note: the revised version of the series adds an introduction by Ann Druyan to this episode, recorded after Sagan's death, in which she discusses some of the changes that occurred in the years after its broadcast.This episode emphasizes astronomy: from the universe to the round Earth.
