  • Effects of Predation on the Niche of Lizards

    Effects of Predation on the Niche of Lizards

    Data Points

    A team of scientists studied the effects of introducing a lizard predator on the food webs of a group of small islands in the Bahamas.

  • Resistance to Coral Bleaching

    Resistance to Coral Bleaching

    Data Points

    This activity analyzes a published scientific figure from a study that tested whether corals can become more resistant to bleaching.

  • Modeling Ecosystem Effects of Termite Mound Patterns

    Modeling Ecosystem Effects of Termite Mound Patterns

    Data Points

    Dr. Corina Tarnita and colleagues studied how a pattern of termite mounds across a dryland ecosystem enhances resilience against desertification.

  • Creating Chains and Webs to Model Ecological Relationships

    Creating Chains and Webs to Model Ecological Relationships

    Card Activities

    Students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level. Also available in Spanish.

  • Coral Reefs and Global Warming

    Coral Reefs and Global Warming

    Lessons

    This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

  • The Lone Anole

    The Lone Anole

    Phenomenal Images

    Students explore a photo of an anole lizard as a phenomenon to explore adaptations and natural selection.

  • Discovering the Wallace Line

    Discovering the Wallace Line

    Lessons

    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 Wallace Line—a sharp boundary that separates distinct Asian and Australian fauna. 

  • Beaks As Tools: Selective Advantage in Changing Environments

    Beaks As Tools: Selective Advantage in Changing Environments

    Labs & Demos

    This classroom experiment supports the film The Origin of Species: The Beak of the Finch. Students collect and analyze data to learn why even slight variations in beak size can make the difference between life and death.

  • Activity for Lizards in an Evolutionary Tree

    Activity for Lizards in an Evolutionary Tree

    Film Activities

    This activity explores the concepts and research on the anole lizards discussed in the short film The Origin of Species: Lizards in an Evolutionary Tree, including adaptation by natural selection, convergent evolution, and the formation of new species.
