  • Virus Hunters: Epidemiology of Nipah Virus

    Virus Hunters: Epidemiology of Nipah Virus

    Activity

    In this activity, students will be exploring cases of Nipah virus (NiV) infection as an epidemiologist would, by collecting evidence and making calculations and predictions, based on scientific data.

  • Viral Lysis and Budding

    Viral Lysis and Budding

    Activity

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

  • HIV Protease Inhibitors

    HIV Protease Inhibitors

    Activity

    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

    Activity

    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

    Activity

    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

    Activity

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

  • Understanding Variation

    Understanding Variation

    Activity

    This lesson complements the film The Biology of Skin Color and discusses variation in human skin color and polygenic inheritance. Also available in Spanish.

  • Zebrafish and Skin Color

    Zebrafish and Skin Color

    Activity

    This lesson complements the film The Biology of Skin Color and explores how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color.

  • Human Skin Color: Evidence for Selection

    Human Skin Color: Evidence for Selection

    Activity

    This case study is based on the short film The Biology of Skin Color. Students use real data to propose hypotheses, make predictions, and justify claims with evidence. Also available in Spanish.

  • How Did Dinosaurs Regulate Their Body Temperature?

    How Did Dinosaurs Regulate Their Body Temperature?

    Activity

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

  • Milk—How Sweet Is It?

    Milk—How Sweet Is It?

    Activity

    In this lab, students test different samples to see which ones contain the lactase enzyme. Also available in Spanish.

  • Pedigrees and the Inheritance of Lactose Intolerance

    Pedigrees and the Inheritance of Lactose Intolerance

    Activity

    Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families. Also available in Spanish.

  • West Nile Virus: Vectors and Hosts Game

    West Nile Virus: Vectors and Hosts Game

    Activity

    Play the West Nile virus game to learn how the virus spreads and how the outcome changes depending on the species that is infected. Resources are also available in Spanish.

  • Beaks As Tools: Selective Advantage in Changing Environments

    Beaks As Tools: Selective Advantage in Changing Environments

    Activity

    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.

  • Using DNA to Explore Lizard Phylogeny

    Using DNA to Explore Lizard Phylogeny

    Activity

    This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are guided to sort the lizard species by appearance, then generate a phylogenetic tree using the lizards’ DNA sequences to evaluate whether species that appear similar are closely related to each other.

  • Lactose Intolerance: Fact or Fiction

    Lactose Intolerance: Fact or Fiction

    Activity

    Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film. Also available in Spanish.

  • Got Lactase? Blood Glucose Data Analysis

    Got Lactase? Blood Glucose Data Analysis

    Activity

    Students interpret the results of two different tests for lactase persistence.

  • Using Genetic Crosses to Analyze a Stickleback Trait

    Using Genetic Crosses to Analyze a Stickleback Trait

    Activity

    A hands-on activity in which students analyze the results of genetic crosses between stickleback fish with different traits.

  • Modeling the Regulatory Switches of the Pitx1 Gene in Stickleback Fish

    Modeling the Regulatory Switches of the Pitx1 Gene in Stickleback Fish

    Activity

    A hands-on activity in which students interpret molecular diagrams and build physical models of eukaryotic gene regulation.

  • Diet and the Evolution of Salivary Amylase

    Diet and the Evolution of Salivary Amylase

    Activity

    Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
