This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

This activity guides the analysis of a published scientific figure from a study that tested how effectively mimicry protects arthropods against different types of predators.

This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

In this activity, students formulate a hypothesis and collect and analyze real research data about how quickly natural selection can act on specific traits in a population as a result of predation. It is accompanied by a short video that describes the experiment this activity is based on.

Several questions are embedded within the short film The Day the Mesozoic Died, which 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.

In this hands-on activity, students analyze the results of genetic crosses between stickleback fish with different traits. It complements the film Evolving Switches, Evolving Bodies.

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.

This activity explores the research described in the short film The Day the Mesozoic Died. The film traces the uncovering of key clues revealing that an asteroid struck Earth 66 million years ago, triggering a mass extinction.

This activity supports concepts covered in the short filmThe Day the Mesozoic Died by replicating observations and measurements made by researchers of fossilized protists, called foraminifera (or forams), below and above the K-T boundary.

This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates.
