Introduction to cancer stem cells in a Q&A format.
In this activity, students learn how cell specialization takes place in vertebrate embryos. They begin by exploring a gallery of different kinds of specialized cells. They also explore how white blood cells are specialized to fight viruses. They learn about the role of master control genes in cell development. Finally, they learn about the significance of -- and controversy surrounding -- stem cell research, and then analyze the different points of view in the stem cell debate.
Using a combination of directed case method and role-playing in which students learn about their roles using the jigsaw technique, this case study teaches about the main concepts of stem cell research and therapy and the political and ethical issues surrounding these subjects. The case begins by describing the riding accident that left actor Christopher Reeve paralyzed and ends by posing a final open-ended question that encourages student debate and discussion. The case can be used in a general biology class, an ethics class, or a public policy class.
The film In Vitro, set thirty years in the future, is about 3 generations of women and the effects that a maverick scientific experiment has on their lives. This resource includes an 18 minute film, lesson plans and additional resources to foster dialogue and discussion.
Students learn about new techniques scientists have devised to derive embryonic stem cells in mice. They then work in groups to explore and report on different types of stem cells used in research today, including embryonic, fetal, umbilical, and adult.
