The Gulf of Mexico dead zone, an area of low oxygen that kills marine life, costs the United States $82 million every year. Young scientists research anoxic ocean environments then come up with a hypothesis for the cause of the Gulf of Mexico dead zone. Scholars design an experiment to test their hypotheses, and a group discussion ensures they have learned the key points.
- Review how to identify valid sources of information on the Internet
- Have students offer suggestions for fixing or preventing further damage to the Gulf of Mexico
- Relies on prior knowledge of the significance of dissolved oxygen in aquatic environments; if scholars don't have this knowledge, add extra time to cover it before or near the beginning of the lesson
- Provides connections to language arts, chemistry, and social studies
- Includes extension ideas
- Offers many resources for further research, experiments, and related lessons
