Hysteria Over Pfiesteria

(Complete Item Description)

Abstract:: Students will be guided through an investigation of the Pfiesteria outbreaks through a variety of approaches employing writing, math, drawing, summarizing and deductive skills. As students assimilate details of the Pfiesteria problem, they will begin to develop a multifaceted understanding of the issue and its potential links to nonpoint source pollution. In Exercise II, they study the spatial and temporal distribution of Pfiesteria outbreaks in an effort to explore reasons for the connection between nonpoint source nutrient pollution and the occurrence of Pfiesteria outbreaks. This will lead them into an exercise investigating their own households as sources of nonpoint source nutrient pollution. Finally students look at real-time data collection efforts to make the connection between the science they read about and actual data interpretation from science labs studying Pfiesteria in North Carolina's rivers.
