Teaching Tips

  • Very short video that can be used to start off a unit on biomes and climate change.

About the Science

  • Describes how succulent plants in the South African Karoo biome are being impacted by recent changes to the climate that make it difficult for these plants to survive.
  • Comments from expert scientist: This is a nice synopsis of the Karoo Biome and how climate change is impacting the succulents in this environment. It also has a helpful explanation of the impacts of the environment on the society that depends on it in terms of impacts on disease, agriculture, and water availability. Though Midgley's model is mentioned early in the video, there is no link to the data or references to find more information.

About the Pedagogy

  • Good quality of explanation and relevant illustrations. Key point: prior infrastructure planning was based on "normal" climate

Technical Details/Ease of Use

  • Very easy to use
  • Video starts automatically when web page opened. Teacher should pause video after ad before playing video in class.

Middle School

Disciplinary Core Ideas: 5

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.

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.

High School

Disciplinary Core Ideas: 6

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.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.

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

HS-LS2.C1:A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability.

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).
