| Description | These lessons for grades 7 to 12 explore scientific and ethical issues in stem cell research. Students are introduced to fundamental stem cell concepts with planaria as a model organism in a laboratory investigation. Students identify stages in the development of human embryos by modeling early growth with play-dough. Using their models, they are then able to compare the types and potency of human stem cells. A variety of techniques for obtaining stem cells are introduced to students though written descriptions, diagrams, and news articles. Students learn the type of stem cells produced by each technique as well as some history of stem cell research. Students become familiar with the history of federal policy and regulation in regard to embryonic stem cell research, the ethical debate which has shaped this policy, and the implications for treatment of disease and advancement of scientific knowledge. The unit culminates with students developing a position through a Decision-Making Framework. Students may write a letter to the President or the President’s Council on Bioethics, or develop a proposal for NIH funding to research treatment for a chosen disease using either embryonic or adult stem cells. | |||
