- Optional extension: students take on the role of organisms such as predators, prey, or plants within a specific ecosystem. Each group is assigned different survival needs, provided by the educator.
About the Science
- Students hear from an Elder who speaks about how he used to go trolling (fishing) for salmon with his relatives when he was young. He recalls that they noticed the salmon were moving farther offshore into deeper water. They suspected it was because the water was warming.
- Comments from expert scientist:
- The description of and connection between the PDO and salmon is a great example!
- The cultural background is excellent!
- The video is a great media use
- Have students define "trolling" and "subsistence"
- I don't think this activity should be used for students older than 8th grade, unless more discussion questions are added about colder waters holding more O2, Western scientific methods, how CO2 warms the planet, added graphics of the PDO, etc.
I think some more specific discussion questions / background info should be included to meet the highest scientific standards, even though these standards are listed in the activity. For instance, nothing is mentioned in the background about climate models. There is also no information about why the climate is changing. I think the only standards met of the ones listed are for grades 6-8, but this could be easily adapted by adding a paragraph about climate model observations, projections and why the climate is warming (simplified).

Disciplinary Core Ideas: 6
MS-ESS2.C1:Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
MS-ESS2.D1:Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns.
MS-ESS3.C1:Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.
MS-LS2.C1:Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
MS-LS2.C2:Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health
MS-LS4.D1:Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.
Disciplinary Core Ideas: 5
HS-ESS2.C1:The abundance of liquid water on Earth’s surface and its unique combination of physical and chemical properties are central to the planet’s dynamics. These properties include water’s exceptional capacity to absorb, store, and release large amounts of energy, transmit sunlight, expand upon freezing, dissolve and transport materials, and lower the viscosities and melting points of rocks.
HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
HS-ESS3.C1:The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.
HS-LS2.C2:Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species.
HS-LS4.D2:Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction).
