  • 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. Also available in Spanish.

  • Using Images as Phenomena

    Using Images as Phenomena

    Activity

    This hands-on activity engages students in asking questions about phenomena using images from the Image of the Week Collection.

  • Scientific Inquiry and Data Analysis Using WildCam Gorongosa

    Scientific Inquiry and Data Analysis Using WildCam Gorongosa

    Activity

    In this activity, students will be guided through making observations from trail camera data in Gorongosa National Park, the development and investigation of a scientifically testable research question, and analysis of their results.

  • Biodiversity Studies in Gorongosa

    Biodiversity Studies in Gorongosa

    Activity

    In this activity, students will calculate species richness, evenness, and the Shannon diversity index for various habitat types using data from trail cameras in Gorongosa National Park, and then investigate the impact of human activity in these habitats.

  • Central Dogma Card Activity

    Central Dogma Card Activity

    Activity

    In this hands-on activity students review the steps of eukaryotic gene expression and learn how this knowledge can be used to treat genetic disease.

  • Seed Dispersal in Tropical Forests

    Seed Dispersal in Tropical Forests

    Activity

    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.

  • Modeling Food Webs in Darién, Panama

    Modeling Food Webs in Darién, Panama

    Activity

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

  • Stalking the Genetic Basis of a Trait

    Stalking the Genetic Basis of a Trait

    Activity

    In this activity students analyze data on the expression of the tb1 gene and use it to formulate an explanation as to how a specific difference in the corn version of the gene explains the phenotype of less branching.

  • 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.

  • 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.
