- Inclusion of a food web diagram would enhance understanding.
- Teachers of younger students may wish to introduce the more advanced vocabulary.
About the Science
- As apex predators, polar bears, walruses, Arctic foxes, and beluga whales are all affected by changes in the Arctic food web as a result of climate change.
- Missing a food web diagram that could explain the effect of changes in predator populations.
Comments from expert scientist:
- Gives many facts on the negative effects of climate change for animals in the arctic: warmer temperatures means retreat of ice earlier, risk of drowning, changes in hunting patterns, forced to swim longer distances to find food, vulnerability to predators, new competition between species, food source changes
About the Pedagogy
- Supplemental materials, including lesson plans, educator guide, background articles, a student workbook, and a curriculum guide are available directly below the video.

Disciplinary Core Ideas: 6
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-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.
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.
