  • Analyzing Data on Tuskless Elephants

    Analyzing Data on Tuskless Elephants

    Lessons

    In this activity, students analyze data to investigate tusklessness in elephant populations.

  • Developing an Explanation for Mouse Fur Color

    Developing an Explanation for Mouse Fur Color

    Lessons

    In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

  • Seed Dispersal in Tropical Forests

    Seed Dispersal in Tropical Forests

    Lessons

    In this activity, students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.

  • Tracking Genetically Modified Mosquitoes

    Tracking Genetically Modified Mosquitoes

    Lessons

    Genetically modified mosquitoes have been used to reduce mosquito populations and the diseases they spread. But how can we tell if the method works? In this activity, students analyze data from a field experiment.

  • The Teosinte Hypothesis

    The Teosinte Hypothesis

    Lessons

    In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.

  • How Did Dinosaurs Regulate Their Body Temperature?

    How Did Dinosaurs Regulate Their Body Temperature?

    Lessons

    This activity uses data from a 2014 scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs. 

  • Living Dinosaurs: Fact or Fiction?

    Living Dinosaurs: Fact or Fiction?

    Lessons

    In this activity, students evaluate and discuss statements about the evolutionary relationship between birds and dinosaurs covered in the short film Great Transitions: The Origin of Birds.

  • 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.

  • Reading Primary Sources: Darwin and Wallace

    Reading Primary Sources: Darwin and Wallace

    Lessons

    This activity serves as a supplement to the HHMI short film The Origin of Species: The Making of a Theory. Students read and analyze excerpts from texts written by Charles Darwin and Alfred Russel Wallace and answer questions about the information presented, developing their nonfiction reading comprehension.

  • Identifying Patterns in Observations

    Identifying Patterns in Observations

    Lessons

    This activity challenges students to identify observations that Darwin and Wallace made during their travels, as shown in the short film The Origin of Species: The Making of a Theory. Students then evaluate claims about evolution by natural selection based on these observations.

  • 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. 

  • Pulse Chase Primer: The Meselson-Stahl Experiment

    Pulse Chase Primer: The Meselson-Stahl Experiment

    Lessons

    This activity can be used in conjunction with the short film The Double Helix. It introduces students to the classic experiment by Matthew Meselson and Franklin Stahl, which revealed that DNA replication follows the semiconservative model.

  • The Making of a Theory—Fact or Fiction

    The Making of a Theory—Fact or Fiction

    Lessons

    This activity supports the viewing of the film The Origin of Species: The Making of a Theory. Before and after watching the film, students discuss and evaluate several statements about Charles Darwin, Alfred Russel Wallace, and the specific evidence that led each of them to the theory of evolution by natural selection.

  • Evolution in Action: Data Analysis

    Evolution in Action: Data Analysis

    Lessons

    These two activities support the film The Origin of Species: The Beak of the Finch. They provide students with the opportunity to analyze data collected by Princeton University evolutionary biologists Peter and Rosemary Grant.

  • Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics

    Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics

    Lessons

    In this activity, students apply concepts pertaining to the genetics of sickle cell disease and its relationship to malaria explored in the short film The Making of the Fittest: Natural Selection in Humans.

  • A Lesson on the Nature of Science

    A Lesson on the Nature of Science

    Lessons

    A worksheet designed to show students how scientists make their discoveries. It provides students with background information about how Dr. Allison's work built upon the contributions made by other scientists. 

  • Testing a Hypothesis

    Testing a Hypothesis

    Lessons

    A worksheet designed to actively engage students as they watch the film. Students are asked to answer questions pertaining to the information provided in the film.

  • Following the Trail of Evidence

    Following the Trail of Evidence

    Lessons

    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.

  • Allele and Phenotype Frequencies in Rock Pocket Mouse Populations

    Allele and Phenotype Frequencies in Rock Pocket Mouse Populations

    Lessons

    A lesson that uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.

  • The Mosquito Life Cycle Activity

    The Mosquito Life Cycle Activity

    Lessons

    In this activity, students study the mosquito life cycle by breeding and observing them and then demonstrate how these data could be used to inform public policy.
