Visitors to this Web site from the US Environmental Protection Agency can learn about the ecological and health concerns associated with mercury. In addition to the resources available on the main Web page, the site also contains a teaching guide. Educators are invited to help "students learn about the health and environmental concerns associated with mercury, find out where it is in their school and homes, and help school officials and family members do something about it." The activities are designed for high school students, but could be modified for younger students.
