  • Vertebrate Declines and the Sixth Mass Extinction

    Vertebrate Declines and the Sixth Mass Extinction

    Data Points

    In this study, researchers measured species population declines on a global scale that may contribute to the sixth mass extinction.

  • 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.

  • 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.

  • Dead Zones in Coastal Ecosystems

    Dead Zones in Coastal Ecosystems

    Data Points

    Researchers overlaid the locations of more than 400 hypoxic systems linked to eutrophication on a map of the global “human footprint.”

  • Written in Chalk

    Written in Chalk

    Phenomenal Images

    Students explore photos of chalk formations and coccolithophore algae as phenomena to explore the interplay between biological and geological processes.

  • Ocean Acidification

    Ocean Acidification

    Labs & Demos

    In this hands-on activity, students simulate the effects of decreasing pH caused by rising levels of atmospheric carbon dioxide.

  • Trends in Atmospheric Carbon Dioxide

    Trends in Atmospheric Carbon Dioxide

    Data Points

    This activity analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2016.

  • Resistance to Coral Bleaching

    Resistance to Coral Bleaching

    Data Points

    This activity analyzes a published scientific figure from a study that tested whether corals can become more resistant to bleaching.

  • Modeling Ecosystem Effects of Termite Mound Patterns

    Modeling Ecosystem Effects of Termite Mound Patterns

    Data Points

    Dr. Corina Tarnita and colleagues studied how a pattern of termite mounds across a dryland ecosystem enhances resilience against desertification.

  • Coral Reefs and Global Warming

    Coral Reefs and Global Warming

    Lessons

    This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

  • Discovering the Wallace Line

    Discovering the Wallace Line

    Lessons

    This activity supports the HHMI short film The Origin of Species: The Making of a Theory. Students are presented with a map of the Malay Archipelago and some field notebooks with observations of animals. By plotting which animals are found on which island, the students discover the Wallace Line—a sharp boundary that separates distinct Asian and Australian fauna. 

  • Earth Systems Activity

    Earth Systems Activity

    Lessons

    This activity guides students through building a conceptual model of how carbon dioxide affects Earth's climate

  • Finding the Crater

    Finding the Crater

    Card Activities

    This hands-on activity requires students to “visit” different K-T boundary sites.

  • What is My Carbon Footprint?

    What is My Carbon Footprint?

    Lessons

    This activity allows students to calculate their carbon footprint using an online calculator.

  • Weighing the Evidence for a Mass Extinction—On Land

    Weighing the Evidence for a Mass Extinction—On Land

    Lessons

    A lesson in which students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the K-T mass extinction.

  • Determining the Size and Energy of the K-T Asteroid

    Determining the Size and Energy of the K-T Asteroid

    Lessons

    A lesson in which students calculate the mass, size, and kinetic energy of the K-T asteroid based on the total abundance of iridium in the K-T boundary layer.

  • Following the Trail of Evidence

    Following the Trail of Evidence

    Lessons

    In this activity, students identify and explain the evidence presented in the short film The Day the Mesozoic Died that led to the discovery that an asteroid struck Earth about 66 million years ago, causing a mass extinction.

  • Weighing the Evidence for a Mass Extinction: In the Ocean

    Weighing the Evidence for a Mass Extinction: In the Ocean

    Card Activities

    This activity supports concepts covered in the short film The Day the Mesozoic Died by replicating observations and measurements made by researchers of fossilized protists, called foraminifera (or forams), below and above the K-T boundary.

  • Calculating Iridium Fallout From an Asteroid Impact

    Calculating Iridium Fallout From an Asteroid Impact

    Lessons

    A worksheet in which students calculate how much iridium was released, and eventually deposited all over the Earth, by the impact of the asteroid that caused the K-T extinction.

  • Distribution of Elements in Earth’s Crust

    Distribution of Elements in Earth’s Crust

    Lessons

    A lesson in which students read a passage and answer questions about the information presented, testing their non-fiction reading comprehension.

  • Chemical Signatures of Asteroid Impacts

    Chemical Signatures of Asteroid Impacts

    Lessons

    A lesson in which students analyze the chemical data that led researchers to conclude that the K-T boundary layer contained an extraordinary concentration of iridium. 

  • Winogradsky columns: Microbial ecology in the classroom

    Winogradsky columns: Microbial ecology in the classroom

    Labs & Demos

    An activity that recreates zones of microbial activity in a glass column. To accompany the lecture series Changing Planet: Past, Present, Future.
