    Why do Some People Inherit a Predisposition to Cancer? A small group activity on cancer genetics
    Before undergraduate students take a genetics course they generally know cancer has a genetic basis and involves the proliferation of cells; however, many are uncertain about why only a subset of people have a predisposition to cancer and how that...

    How Do Kidneys Make Urine From Blood? Qualitative and Quantitative Approaches to Filtration, Secretion, Reabsorption, and Excretion
    The function of the kidneys is to help maintain a constant internal environment (homeostasis) by regulating the volume and chemical composition of the blood. This regulation occurs via three fundamental processes: filtration, secretion, and...

    Interactive Video Vignettes (IVVs) to Help Students Learn Genetics Concepts
    Many video resources exist to teach Mendelian genetics, but most consist of passive delivery of information rather than active construction of knowledge by users. We have created two interactive video vignettes (IVVs) that can be used together or...

    Furry with a chance of evolution: Exploring genetic drift with tuco-tucos
    Genetic drift is an important mechanism of evolution, yet undergraduates often fail to understand how it leads to evolutionary change due in part to its random nature. This lesson plan describes a simulation-based activity that allows students to...
