The disappearance of the dinosaurs at the end of the Cretaceous period posed one of the greatest, long-standing scientific mysteries. This three-act film tells the story of the extraordinary detective work that solved it.
The following classroom-ready resources complement The Day the Mesozoic Died, which tells the story of the extraordinary detective work that led to the stunning discovery that an asteroid struck Earth 66 million years ago, triggering a mass extinction of animals, plants and even...
A short article by Dr. Sean B. Carroll detailing the discoveries covered in the film The Day The Mesozoic Died.
Has Earth changed over deep time? How did Earth shape life and life shape Earth? What does Earth's climate in the distant past tell us about the future?
The theory of plate tectonics took many decades to become accepted. The process by which it was finally accepted provides a fascinating glimpse into how scientists build new scientific consensus.
Scientific evidence for global climate change is overwhelming, yet the American public remains skeptical. History provides insights into how a Cold War-era think tank became an influential source of anti-regulation sentiment.
Students discuss the short film after a screening at the 2012 Holiday Lectures on Science.
Continents rose in elevation after ice sheets from the last ice age retreated. This suggested that the underlying mantle is pliable.
The concept that continents float on a pliable mantle is an important element of the theory of continental drift.
An early model of continental drift proposed that parts of continental plates can sink into the mantle, allowing for movement.
An early continental drift model proposed that mantle convection can produce continental movement and new plate formation.
This hands-on activity requires students to “visit” different K-T boundary sites.
Plate tectonics is the unifying theory of Earth science.
This activity supports the viewing of the film The Origin of Species: The Making of a Theory. Before and after watching the film, students discuss and evaluate several statements about Charles Darwin, Alfred Russel Wallace, and the specific evidence that led each of them to the theory...
This activity supports the HHMI short film The Origin of Species: The Making of a Theory. Students are presented with a map of the Malay Archipelago and some field notebooks with observations of animals. By plotting which animals are found on which island, the students discover the...
The story of Alfred Wegener, who came up with the idea that continents once formed a single landmass and had drifted apart.
Embedded quiz modules test students’ understanding as they watch the short film on the asteroid that caused the extinction of the dinosaurs.
