    Click & Learn

    Download the accompanying student worksheet under "Downloads." What did Earth look like 250 million years ago? Or 1 billion years ago? Or 4.5 billion years ago? EarthViewer is an interactive tool that allows you to explore the science of Earth's deep history.

  • Ocean Acidification

    Ocean Acidification

    Activity

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

  • Earth Systems Activity

    Earth Systems Activity

    Activity

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

  • Geological History of Oxygen

    Geological History of Oxygen

    Click & Learn

    Explore the changes in oxygen levels throughout Earth’s history and discover their impact on life.

  • The Day the Mesozoic Died

    The Day the Mesozoic Died

    Short Film

    (33 min 43 sec) The disappearance of the dinosaurs at the end of the Cretaceous period posed one of the greatest, long-standing scientific mysteries. This three-act film tells the story of the extraordinary detective work that solved it. Also available in Spanish.

  • Earth's Climate: Back to the Future

    Earth's Climate: Back to the Future

    Lecture

    (1 hr 27 min 59 sec) Earth has been both cooler and warmer in the past, but the change is usually gradual. The current rate of carbon dioxide increase is unprecedented in human history, and solutions to mitigate its effect on global warming are challenging to implement.

  • Calculating Iridium Fallout From an Asteroid Impact

    Calculating Iridium Fallout From an Asteroid Impact

    Activity

    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

    Activity

    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

    Activity

    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

    Activity

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

  • Ice Crystal Formation in Icefish and Non-Icefish Blood

    Ice Crystal Formation in Icefish and Non-Icefish Blood

    Activity

    A dramatic demonstration that simulates how tiny ice crystals would form and grow in the blood of most fish if they ventured into the icy waters of the Antarctic.

  • Screening chemical libraries with robotics

    Screening chemical libraries with robotics

    Clip

    (1 min 24 sec) Robotic equipment makes it possible to screen massive chemical libraries in just a matter of days.

  • Molecular Structure of Fat

    Molecular Structure of Fat

    Click & Learn

    This slide show delves into the various molecular shapes that fat can take.

  • Paired DNA strands

    Paired DNA strands

    Animation

    (1 min 18 sec) DNA has a double helix structure. If untwisted, DNA looks like two parallel strands. Each strand has a linear sequence of A, C, G, and T. The precise order of the letters carries the coded instructions. One strand is a complementary image of the other: A always pairs with T, and C always pairs with G.

  • Scanning Life's Matrix: Genes, Proteins, and Small Molecules

    Scanning Life's Matrix: Genes, Proteins, and Small Molecules

    Lecture

    In four presentations, Stuart L. Schreiber, PhD, and Eric S. Lander, PhD, open a window onto the fast-paced world of genomic science and chemical genetics.

  • Rapamycin

    Rapamycin

    Animation

    (1 min 10 sec) Rapamycin is a small molecule originally isolated from nature. It has antibiotic and immunosuppressive properties. It also allows two proteins which do not normally interact to bind together in the cell, which causes problems in the nutrient-sensing pathway.

  • The Double Life of RNA

    The Double Life of RNA

    Lecture

    In four lectures, Nobel laureate Thomas R. Cech, PhD, discusses the ability of RNA to act as more than just an intermediary between DNA and proteins.
