  • 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.

  • What van Leeuwenhoek Saw

    What van Leeuwenhoek Saw

    Activity

    This hands-on activity helps students understand concepts related to building scale models by using cards of microorganisms and cells that were first visualized by Antonie van Leeuwenhoek.

  • Tracking Genetically Modified Mosquitoes

    Tracking Genetically Modified Mosquitoes

    Activity

    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.

  • Developing an Explanation for Mouse Fur Color

    Developing an Explanation for Mouse Fur Color

    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. 

  • Modeling Trophic Cascades

    Modeling Trophic Cascades

    Activity

    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

    Activity

    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

    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.

  • DNA Profiling Activity

    DNA Profiling Activity

    Activity

    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. 

  • Ebola: Disease Detectives

    Ebola: Disease Detectives

    Activity

    In this classroom activity, students will analyze sequences of Ebola viruses isolated from patients in Sierra Leone during the Ebola outbreak of 2013–2016 to track the virus spread. Also available in Spanish.

  • The Great Elephant Census Modeling Activity

    The Great Elephant Census Modeling Activity

    Activity

    In this classroom activity, students will model two types of counting methods, sample counts and total counts, to determine population size. 

  • 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 Impacts on Biodiversity

    Human Impacts on Biodiversity

    Activity

    In this activity, students will use trail camera data to answer a scientific research question about the impacts of humans on species diversity in Gorongosa.

  • Niche Partitioning Activity

    Niche Partitioning Activity

    Activity

    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.

  • Spreadsheet Tutorial 5: Histogram
