This video shows the reactions of first-grade students to a replica of a Tiktaalik fossil.

This activity explores the concepts and research presented in the short film Great Transitions: The Origin of Tetrapods. The film describes the discovery of Tiktaalik, a key fossil that illuminates the evolutionary history of four-legged animals.

This film describes the discovery of Tiktaalik, a key fossil that illuminates the evolutionary origins of four-legged animals.

This interactive module explores different anatomical features of the human body and what they reveal about the evolutionary history of humans.

This activity explores the concepts and research presented in the short film The Origin of Species: The Making of a Theory, which documents the epic voyages of naturalists Charles Darwin and Alfred Wallace.

This film explores the epic voyages of Darwin and Wallace that led each to independently propose the natural origin of species and formulate the theory of evolution by natural selection.

This film explores how mutations in gene regulatory regions have resulted in major changes in the anatomy of freshwater populations of stickleback fish.

This film tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

This interactive module explores key events in the record of life on Earth, which stretches over three billion years.

In this video, Tyler Lyson describes and demonstrates how he and other paleontologists uncover fossils from prehistoric animals, including dinosaurs.

This activity supports concepts covered in the short film The Day the Mesozoic Died. Students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the mass extinction that marked the end of the age of the dinosaurs.

In this activity, students identify and explain the evidence presented in the short film The Day the Mesozoic Died that led to the discovery that an asteroid struck Earth about 66 million years ago, causing a mass extinction.
