  • HIV Protease Inhibitors

    HIV Protease Inhibitors

    Activities

    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

    Activities

    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

    Activities

    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

    Activities

    This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

  • Ocean Acidification

    Ocean Acidification

    Activities

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

  • Efficacy of a Treatment for Chronic Myeloid Leukemia

    Efficacy of a Treatment for Chronic Myeloid Leukemia

    Data Points

    Dr. Brian Druker and colleagues monitored white blood cell counts in six patients with chronic myeloid leukemia treated with the drug, STI571, which blocks the activity of the cancer-causing tyrosine kinase BCR-ABL.

  • Earth Systems Activity

    Earth Systems Activity

    Activities

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

  • Lactose Intolerance: Fact or Fiction

    Lactose Intolerance: Fact or Fiction

    Activities

    Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film. Also available in Spanish.

  • Got Lactase? Blood Glucose Data Analysis

    Got Lactase? Blood Glucose Data Analysis

    Activities

    Students interpret the results of two different tests for lactase persistence.

  • Calculating Iridium Fallout From an Asteroid Impact

    Calculating Iridium Fallout From an Asteroid Impact

    Activities

    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

    Activities

    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

    Activities

    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

    Activities

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

  • Diet and the Evolution of Salivary Amylase

    Diet and the Evolution of Salivary Amylase

    Activities

    Students explore the effects of different diets on the evolution of an enzyme that breaks down starch. Also available in Spanish.

  • How Do Fibers Form?

    How Do Fibers Form?

    Activities

    A hands-on activity in which students construct models of sickle-cell hemoglobin fibers inside red blood cells to illustrate how changes in the structure of a protein can affect cell shape. Students are then asked to relate these changes to disease symptoms. Also available in Spanish.

  • Ice Crystal Formation in Icefish and Non-Icefish Blood

    Ice Crystal Formation in Icefish and Non-Icefish Blood

    Activities

    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.

  • Natural Selection and Evolution of Rock Pocket Mouse Populations

    Natural Selection and Evolution of Rock Pocket Mouse Populations

    Activities

    An activity in which students analyze amino acid data and draw conclusions about the evolution of coat color phenotypes in different rock pocket mouse populations.

  • Biochemistry and Cell Signaling Pathway of the Mc1r Gene

    Biochemistry and Cell Signaling Pathway of the Mc1r Gene

    Activities

    An advanced lesson that requires students to analyze partial DNA sequences of the Mc1r gene and identify the effects of mutations on the MC1R protein pathway.
