    Film Guides: The Double Helix

    Film Guides

    The following classroom-ready resources complement The Double Helix. This short film describes the evidence that led James Watson and Francis Crick to the discovery of the double-helical structure of DNA and how the structure immediately revealed how genetic information is stored and inherited.

  • Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics

    Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics

    Activities

    A lesson that requires students to work through a series of questions pertaining to the genetics of sickle cell disease and its relationship to malaria. These questions will probe students' understanding of Mendelian genetics, probability, pedigree analysis, and chi-square statistics. Also available in Spanish.

  • Testing a Hypothesis

    Testing a Hypothesis

    Activities

    A worksheet designed to actively engage students as they watch the film. Students are asked to answer questions pertaining to the information provided in the film.

  • Population Genetics, Selection, and Evolution

    Population Genetics, Selection, and Evolution

    Activities

    A hands-on activity that uses simulations with beads to teach students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. Also available in Spanish.
