In this self-paced lesson, students learn how environmental factors affect the health of living things, including humans.

In this video segment adapted from Lead Awareness for Parents by the Coalition to Prevent Lead Poisoning, learn about potential effects of lead exposure and how to reduce impacts. A physician describes ways that children are commonly exposed to lead and how elevated blood lead levels can affect their health. Hear about methods to reduce the incidence and severity of lead poisoning, including routine blood testing, home inspections, and proper nutrition. Includes background essay and discussion questions.

This video segment adapted from Playing with Poison describes how children in the Yaqui Valley, one of the largest farming areas in Mexico, have been harmed by chronic exposure to pesticides. To study the long-term health effects of agricultural pesticides, anthropologist Elizabeth Guillette tested children in the Yaqui Valley. The children showed deficits in hand-eye coordination, visual perception, and motor skills. Children in a nearby area that uses little or no pesticides did not share these problems. In North American cities, Guillette saw similar patterns with children exposed to pesticides from indoor spraying and food residue. Includes an essay and discussion questions. [4:58]

Learn about the PCB cleanup of South Park, a Seattle neighborhood along the Duwamish River, in this video segment adapted from FRONTLINE: Poisoned Waters. In 2004, the community learned that some of its streets and yards were contaminated with toxic chemicals called PCBs. Citizens, galvanized by the finding, demanded the long-promised cleanup of an abandoned asphalt plant.
