    Phenomenal Images

    Students explore photos of a sea slug and chloroplasts as phenomena to explore photosynthesis concepts.

  • Resistance to Coral Bleaching

    Resistance to Coral Bleaching

    Data Points

    To test whether corals can become more resistant to bleaching, Dr. Steve Palumbi and colleagues performed a series of experiments in the U.S. National Park of American Samoa off of Ofu Island. Worksheets also available in Spanish.

    Exploring Biomes in Gorongosa National Park

    Lessons

    Gorongosa National Park in Mozambique is a region with high ecological diversity that encompasses two distinct biomes. This activity introduces students to the concept of biomes in conjunction with the Gorongosa National Park interactive map click and learn

  • Coral Bleaching Activity

    Coral Bleaching Activity

    Lessons

    This is a classroom activity in which students use authentic data to assess the threat of coral bleaching around the world. It supports the 2014 Holiday Lectures on Science video featuring Dr. Stephen Palumbi. Also available in Spanish.

  • 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.
