  • Tracking Genetically Modified Mosquitoes

    Tracking Genetically Modified Mosquitoes

    Activities

    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.

  • Modeling Trophic Cascades

    Modeling Trophic Cascades

    Activities

    Students use cards of animal and plant species to model trophic cascades. Species examples are drawn from seven different habitats to test student understanding.

  • Patterns in the Distribution of Lactase Persistence

    Patterns in the Distribution of Lactase Persistence

    Activities

    Students explore the geographic distribution of lactase persistence around the world by analyzing real data collected by scientists.

  • Viral Lysis and Budding

    Viral Lysis and Budding

    Activities

    This activity outlines two demonstrations that model how enveloped and nonenveloped viruses are released from infected cells.

  • HIV Protease Inhibitors

    HIV Protease Inhibitors

    Activities

    This demonstration models how the HIV protease enzyme functions and how its activity is blocked by a class of anti-HIV drugs.

  • Viral DNA Integration

    Viral DNA Integration

    Activities

    In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.

  • HIV Reverse Transcription and AZT

    HIV Reverse Transcription and AZT

    Activities

    Students model how the anti-HIV drug AZT (azidothymidine) interferes with the process of viral replication.

  • HIV Receptors and Co-receptors

    HIV Receptors and Co-receptors

    Activities

    This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

  • DNA Profiling Activity

    DNA Profiling Activity

    Activities

    This multi-part lesson is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world. 

  • Niche Partitioning Activity

    Niche Partitioning Activity

    Activities

    Students are introduced to real-world examples of niche partitioning and cutting-edge technology used to give unprecedented insights into the feeding habits of wild animals.

  • Ocean Acidification

    Ocean Acidification

    Activities

    In this hands-on activity, students simulate the effects of decreasing pH caused by rising levels of atmospheric carbon dioxide.

  • The Teosinte Hypothesis

    The Teosinte Hypothesis

    Activities

    In this lesson, students work through the mathematics and concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize. Also available in Spanish.

  • Human Feet Are Strange

    Human Feet Are Strange

    Activities

    In this hands-on activity students examine the evidence for the evolution of human bipedality as revealed by a trail of fossil footprints. Also available in Spanish.

  • How Did Dinosaurs Regulate Their Body Temperature?

    How Did Dinosaurs Regulate Their Body Temperature?

    Activities

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

  • Creating Chains and Webs to Model Ecological Relationships

    Creating Chains and Webs to Model Ecological Relationships

    Activities

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

  • Living Dinosaurs: Fact or Fiction?

    Living Dinosaurs: Fact or Fiction?

    Activities

    Students evaluate and discuss statements about the evolutionary relationship between birds and dinosaurs and other facts about these groups, before and after watching the short film Great Transitions: The Origin of Birds. Also available in Spanish.

  • Look Who's Coming for Dinner: Selection by Predation

    Look Who's Coming for Dinner: Selection by Predation

    Activities

    This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are asked to formulate a hypothesis, and collect and analyze real research data to understand how quickly natural selection can act on specific traits in a population. Also available in Spanish.

  • Coral Bleaching Activity

    Coral Bleaching Activity

    Activities

    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.

  • Reading Primary Sources: Darwin and Wallace

    Reading Primary Sources: Darwin and Wallace

    Activities

    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.
