Stressed Out!

Type of Resource



In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.

Performance Expectations

HS-LS2-7   Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.

HS-ESS3-4   Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

MS-LS2-4   Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

HS-ETS1-3   Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.

MS-ESS3-4   Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
