Can we revive Lake Erie's "Dead Zone?"

The Ohio State University Ohio Sea Grant Education Program


This Ohio Sea Grant website features a WebQuest-like activity that explores the development of a dead zone, an oxygen-deprived area where there is no life, in Lake Erie. The activity aims to teach students about the processes that contribute to the development of the dead zones in Lake Erie and examine a decision making process to determine how to treat or cure the dead zone. Links to a teacher page (with a lesson plan and resources) and student page (with references and instructions) are included.
