Into the Dead Zone

Ask a Question

  • This unit about dead zones includes a series of videos about the sources of pollution flowing into the Chesapeake Bay, lesson plans about oyster reef ecology and an urbanized water cycle, worksheets, and activities.
  • There are also resources about careers in science and about youth taking action on this site.
Teaching Tips


  • There is enough content here for an entire unit on water pollution, allowing you to pick and choose the videos, lessons, and activities that work best for your classes.

Additional Prerequisites

  • Teachers will need to print off the included worksheets for the activities and associated lessons.


  • The videos include closed captioning and playback speed control for students with learning differences or ELL students.
  • Social studies classes could use the videos to connect many different human activities to sources of pollution that affect some communities more than others.
  • Science classes could use the videos, activities, worksheets, and lessons to enhance lessons about the water cycle, nitrogen cycle, phosphorus cycle, limiting nutrients, eutrophication, and nonpoint pollution.
  • Other resources on this topic include this PBS video and this water quality activity guide.
Scientist Notes
There is no citation for "400 dead zones have been identified globally."  All the videos in the resource contain relevant information to take action to restore our watersheds, rivers, bays, and oceans. This resource is recommended for teaching.
  • Science
    • ESS2: Earth's Systems
      • 6.ESS2.4 Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity.
      • HS.ESS2.2 Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth systems.
      • HS.ESS2.5 Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.
    • ESS3: Earth and Human Activity
      • 6.ESS3.3 Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
      • HS.ESS3.6 Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity (i.e., climate change).
    • LS2: Ecosystems: Interactions, Energy, and Dynamics
      • 7.LS2.4 Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
      • HS.LS2.6 Evaluate claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
      • HS.LS2.8 Evaluate evidence for the role of group behavior on individual and species’ chances to survive and reproduce.
