Ages 5–7
Midnight Sun & Polar Night
Know that at the poles, daylight and darkness are extreme — in summer the Sun never fully sets (midnight sun) and in winter the Sun never rises (polar night lasting months) — and that this is very different from what we experience at home,…

Polar Animals
Know about other polar animals besides penguins and polar bears — seals that swim under ice, walruses with long tusks, Arctic foxes that turn white in winter, snowy owls, narwhals with their unicorn-like tusk, and whales that migrate to po…

Inuit & Sami Peoples
Know that indigenous peoples have lived in the Arctic for thousands of years — the Inuit across Canada, Alaska, and Greenland, and the Sami in northern Scandinavia — developing remarkable knowledge of the environment, using dog sleds and k…

Ages 7–9
Polar Food Chains
Understand polar food chains — in the Antarctic, phytoplankton are eaten by krill, krill are eaten by fish and penguins, and penguins are eaten by leopard seals and orcas; in the Arctic, algae under ice feeds zooplankton, which feeds fish,…

The Race to the South Pole
Know the story of the race to the South Pole in detail — Norwegian Roald Amundsen and British Robert Falcon Scott both set out in 1911, Amundsen arrived first on 14 December using dog sleds and careful planning, Scott arrived 34 days later…

Ages 7–9
Why Polar Seasons Are Extreme
Understand why the poles have extreme seasons — Earth's axis is tilted at about 23.5°, so as it orbits the Sun, each pole spends half the year tilted toward the Sun (continuous daylight, warmer summer) and half tilted away (continuous dark…

Antarctic Treaty & Research
Know that Antarctica is governed by the Antarctic Treaty (signed 1959, in force since 1961) — which sets Antarctica aside for peaceful purposes and scientific research, bans military activity and mining, and is signed by over 50 countries;…

Climate Change at the Poles
Understand how climate change is affecting polar regions — Arctic sea ice is shrinking dramatically (losing about 13% per decade since 1979), the Greenland and Antarctic ice sheets are losing mass and contributing to sea level rise, permaf…

Ages 9–11
Earth's Frozen Water
Understand the cryosphere and its role in Earth's water system — the cryosphere is all frozen water on Earth (ice sheets, glaciers, sea ice, permafrost, snow cover); polar ice sheets hold about 69% of Earth's fresh water; if all polar ice…

Polar Climate Zone
Understand that polar regions belong to the polar climate zone — one of Earth's five main climate zones (tropical, arid, temperate, continental, polar) — characterised by temperatures rarely above 10°C even in summer, low precipitation (po…

Polar Conservation & Future
Understand the conservation challenges facing polar regions — marine protected areas in the Southern Ocean aim to preserve Antarctic ecosystems, Arctic nations dispute sovereignty over northern sea routes and resources as ice retreats, ind…

Polar Exploration Then & Now
Compare historical polar exploration with modern polar science — the Heroic Age (1897–1922) relied on ships, dogs, and human endurance with many fatalities, while today's polar scientists use GPS, satellites, icebreaker ships, heated resea…

Polar Oceans and World Climate
Understand how polar oceans connect to the global climate system — cold, dense polar water sinks and drives thermohaline circulation (a global conveyor belt of ocean currents), sea ice reflects sunlight back to space (the albedo effect) he…
