  • Developing an Explanation for Mouse Fur Color

    Developing an Explanation for Mouse Fur Color

    Activities

    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

    Activities

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

  • Scientists at Work Guide

    Scientists at Work Guide

    Resource Guides

    A guide to BioInteractive’s Scientists at Work series of videos aligned to relevant curriculum standards.

  • The Search for a Mutated Gene

    The Search for a Mutated Gene

    Scientists at Work

    (8 min 54 sec) How do you identify the disease-causing mutation in a patient with an inherited disease? This video illustrates the steps involved—testing for genes that are the “usual suspects,” searching for mutations in novel genes, and assessing links between genotype and phenotype.

  • 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.

  • Microbial Community Response to an Oil Spill

    Microbial Community Response to an Oil Spill

    Data Points

    Researchers monitored the succession of the microbial community in the Gulf of Mexico using data from before, during, and after the Deepwater Horizon oil spill.

  • Using Wolbachia to Suppress Mosquito Fertility

    Using Wolbachia to Suppress Mosquito Fertility

    Data Points

    In this study, researchers tested whether releasing Wolbachia-infected male Aedes albopictus (Asian tiger mosquitoes) would suppress populations of this mosquito species in their study area.

  • How Lizards Find Their Way Home

    How Lizards Find Their Way Home

    Scientists at Work

    (8 min 33 sec) When Dr. Manuel Leal removed lizards from an area in the forest, he noticed an interesting phenomenon: all the lizards seemed to be back the next day. Watch as he sets up an experiment to study how these lizards navigate home. Also available in Spanish.

  • WildCam Darién

    WildCam Darién

    Click & Learn

    Researchers in Darién and Soberanía National Parks use remote trail cameras to study jaguars and their prey. You can contribute to this important research through WildCam Darién, an online citizen science platform.

  • Sleep Clears β-amyloid from the Brain

    Sleep Clears β-amyloid from the Brain

    Data Points

    The researchers in this study tested whether the rate of Aβ removal is higher during sleep using mice as model organisms. Worksheets also available in Spanish.

  • Trophic Cascades in Salt Marsh Ecosystems

    Trophic Cascades in Salt Marsh Ecosystems

    Scientists at Work

    (10 min 1 sec) Ecologist Brian Silliman uses manipulative field experiments to reveal that salt marsh ecosystems are under top down control from consumers and predators.

  • Riverine Food Webs – How Flow Rates Affect Biomass

    Riverine Food Webs – How Flow Rates Affect Biomass

    Scientists at Work

    (9 min 15 sec) Ecologist Mary Power studies the Eel River in Northern California to figure out the connection between river flows and biodiversity.

  • Mimicry in a Diverse Community of Arthropods

    Mimicry in a Diverse Community of Arthropods

    Data Points

    Researchers exposed arthropod mimics that use a golden patch to warn of unpalatability to predators with different prey preferences to determine how effective their warnings were.

  • Snail Fronts and Salt Marsh Die-Offs

    Snail Fronts and Salt Marsh Die-Offs

    Data Points

    Researchers studied whether periwinkle snail fronts expand mudflats and contribute to salt marsh die-offs.

  • Tracking Global Changes in Forest Cover

    Tracking Global Changes in Forest Cover

    Data Points

    Researchers used satellite imagery analyze the amount of forest that was lost annually across the globe between 2000 and 2012.

  • Studying Elephant Communication

    Studying Elephant Communication

    Scientists at Work

    (6 min 43 sec) Elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Scientists are studying whether elephants can “hear” and interpret these ground vibrations.

  • Cell Division and Cancer Risk

    Cell Division and Cancer Risk

    Data Points

    Cancer is typically attributed to hereditary and environmental factors, but these only explain a fraction of overall cancer risk. In this study, researchers investigated how a third factor—chance genetic mutations that occur during stem cell division—may contribute to the overall rate of cancer incidence in different body tissues.

  • Bat Echolocation

    Bat Echolocation

    Data Points

    In this study, researchers tested whether bats change their behavior while hunting based on feedback from echolocation.
