  • Metabolic Rates

    Cellular Processes

    Students investigate Kleiber's Law — that metabolic rate scales to ~the ¾ power of body mass — using real data from the AnAge Database, working through a five-part packet of...

  • Homeostasis

    Cellular Processes

    Students analyze real physiological data from ten participants who stood up during a lab study (a cardiovascular challenge), tracking heart rate, blood pressure, respiratory...

  • The Cellular Energy Economy

    Cellular Processes

    Students model the three stages of aerobic respiration through a "cellular economy" simulation, earning ATP/NADH/FADH₂ tokens, then pool yield data into a class spreadsheet,...

  • Comparing and Conserving Biodiversity

    Ecology & Populations

    Uses real species-occurrence data from four contrasting ecosystems (Amazon, Appalachian forest, Great Barrier Reef, Arctic tundra) to calculate species richness, analyze...

  • Population Ecology

    Ecology & Populations

    Uses 90 years of real hare–lynx population data from the Canadian boreal forest to help students understand why populations never grow indefinitely, identifying carrying...

  • BRCA Gene Mutations

    Genetics & Heredity

    Uses 30 real variants from the BRCA Exchange to have students classify mutations by type (silent, missense, nonsense, frameshift, splice site), connect each to its protein...

  • Cladograms

    Evolution & Ancestry

    Teaches that building an evolutionary family tree requires distinguishing traits inherited from a common ancestor from traits that evolved independently in similar environments...

  • Evolution at Warp Speed

    Evolution & Ancestry

    A good wrap-up to the evolution unit by tracking how SARS-CoV-2 variants rose and fell (2020–2022), letting students see variation, differential reproduction, and competitive...

  • Fossil Record

    Evolution & Ancestry

    Puts students in the role of the scientist who re-checked the textbooks: using real fossil measurements and a predictive regression model built from living fish, they calculate...

  • Finch Evolution

    Evolution & Ancestry

    Uses 37 years of real beak-measurement data from Darwin's finches to show students that natural selection is a measurable, ongoing process visible within a human lifetime. By...

  • Testing Mendel's Data

    Genetics & Heredity

    Students analyze Mendel's original F2 data to identify inheritance patterns, calculate expected outcomes using probability, and apply chi-square analysis to test whether...
