  • Film Guide for Some Animals are More Equal than Others

    Film Guide for Some Animals are More Equal than Others

    Film Guide

    The following classroom-ready resources complement the film Some Animals Are More Equal Than Others: Trophic Cascades and Keystone Species. It tells the story of the bold experiments by Robert Paine and James Estes, which established the importance of keystone species in regulating ecological communities and the cascades of effects set in motion by their removal.

  • Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Short Film

    (19 min 29 sec) Keystone species and trophic cascades are fundamental concepts in ecology. This short film tells the story of how these concepts were first established through the pioneering experiments of two young researchers: Robert Paine and James Estes.

  • Gorongosa: Using Citizen Science to Study Ecology

    Gorongosa: Using Citizen Science to Study Ecology

    Short Course

    This course connects you to actual ecological research in Gorongosa National Park in Mozambique. Gorongosa was once a thriving national park, until decades of war decimated the park’s large...

  • Lesson 8 - WildCam Gorongosa: Data Analysis

    Lesson 8 - WildCam Gorongosa: Data Analysis

    Activity

    In this activity, students will collect actual data from WildCam Gorongosa and use those data to create graphs and answer an ecological question of their choice.

  • Lesson 7 - Observations Across Habitats

    Lesson 7 - Observations Across Habitats

    Activity

    In this lesson, students will compare wildlife in two different habitats by making observations using sets of trail camera photos. They will then use these observations to formulate questions for further study.

  • Lesson 3 - Scientific Inquiry with WildCam Gorongosa

    Lesson 3 - Scientific Inquiry with WildCam Gorongosa

    Activity

    In this lesson, students will use WildCam Gorongosa to start making observations and generating scientific questions using a single trail camera photo.
