    Activities

    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.

  • New Laetoli Footprints and Hominin Body Size

    New Laetoli Footprints and Hominin Body Size

    Data Points

    Scientists were excavating a site in Laetoli, Tanzania when they uncovered two new sets of hominin tracks located about 150 meters south of the tracks found by Mary Leakey in the 1970’s. They estimated the heights of the two individuals using the size and shape of the footprints.

  • Think Like a Scientist: Gorongosa

    Think Like a Scientist: Gorongosa

    Scientists at Work

    This short video tells the story of how a large-scale project to restore the wildlife of Gorongosa National Park began and describes the project’s approach of combining traditional conservation biology methods with solutions for addressing challenges in the community.

    Click & Learn

    This interactive explores niche partitioning as a mechanism that enables similar species of animals to coexist.

  • Maternal Microbiota Impacts Offspring Immune System

    Maternal Microbiota Impacts Offspring Immune System

    Data Points

    In this study, scientists compared two populations of pregnant mice, one which was kept germ-free throughout pregnancy and the other which was exposed during pregnancy to a strain of E. coli to determine whether the immune systems of offspring begin to develop in utero. Worksheets also available in Spanish.

  • Seed Dispersal in Tropical Forests

    Seed Dispersal in Tropical Forests

    Activities

    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.

  • Role of p53 in the Cell Cycle

    Role of p53 in the Cell Cycle

    Data Points

    Researchers investigated the role of p53 in cell cycle regulation by genetically engineering a cell line with deleted copies of the p53 gene. They exposed the cell lines to DNA-damaging radiation and observed how this exposure impacted mitosis. Worksheets also available in Spanish.
