The NOVA documentary "Search for a Safe Cigarette" recounts the tobacco industry's decades-long attempt to engineer a safer cigarette. This companion Web site offers a number of interesting and informative features, as well as a lesson plan for grades 5-8 and 9-12. The interactive feature titled Anatomy of a Cigarette offers a fascinating tour of the conventional cigarette and two "safer" versions. The Web site also includes: a review of the safer cigarette's "checkered pedigree;" an animated introduction to physiological effect of nicotine on the brain; and a virtual laboratory where visitors can explore the basics of combustion. The lesson plan, which may be used independently of the NOVA program, has students examine government action on tobacco issues and consider the role of government in public health.
