Windows to the Universe/NBC Learn, National Earth Science Teachers Association (NESTA)

The video addresses impact of warming temperatures on major lakes of the world with specific focus on Lake Superior and Lake Tanganyika. It discusses the science of water stratification and its impact on lake ecosystems and on human populations whose livelihoods depend on the lakes.

Video length: 5:13 min.

Teaching Tips

  • Teacher should ensure that they are familiar with any technical terminology.

About the Science

  • The video describes how atmospheric warming is contributing to lake warming. The results of this warming is water stratification, which impacts the food chain and water mixing.
  • Researchers use buoys to collect data such as wind speed, air and water temperature, and cloud cover.
  • Comments from expert scientist: Accurate information, qualified by appropriate disclaimers in most cases. Could have clearer identification of assumptions and other limiting factors or uncertainties.

About the Pedagogy

  • The vocabulary and conceptual level of the content is high with technical terms like stratification and upwelling.

Technical Details/Ease of Use

  • The video is high quality and easy to use.
  • A transcript is available, providing another avenue to access the content.

Middle School

Disciplinary Core Ideas: 3

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.

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-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.

High School

Disciplinary Core Ideas: 6

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-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.

HS-ESS2.E1:The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it.

HS-ESS3.C1:The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.

HS-LS4.D1:Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value.
