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 research stations, and aircraft; understand that modern challenges include studying climate change data, and that polar science now includes diverse international teams including women scientists like glaciologist Liz Thomas and marine biologist Sylvia Earle

Quick check

Can the learner compare old polar exploration — dog sleds, freezing camps, real danger of death — with modern polar science using satellites, heated research stations, and diverse international teams?

The approach

For ages 9–11, compare Heroic-Age polar exploration (c.1897–1922: wooden ships, dog sleds, man-hauling, sextants, furs, and high fatality) with modern polar science (GPS, satellites, icebreakers, ice-core drills, heated research stations, aircraft, and diverse international teams). The core insight is that better tools change not just how safely people work but the QUESTIONS science can ask — shifting from 'can we reach the Pole and survive?' to 'what is happening to the ice and climate, and why?'. Learners compare across clear dimensions (purpose, technology, danger, who takes part), name specific technologies and how each enables survival or new measurement, identify a modern scientist to update the image of who does polar science, and transfer the idea to a new case.

Common misconceptions

  • Polar exploration ended with the Heroic Age — it continues as high-tech international science
  • Modern polar work is just easier sightseeing — it is demanding scientific research, especially on climate
  • Explorers were all men — today's diverse teams include leading women scientists
  • New technology only makes old goals safer — it also changes what questions science can ask
  • The point was always science — the Heroic Age was largely about reaching places first and surviving

Useful representations

  • Then/now toggle: sextant/dogs/wooden ship ↔ GPS/icebreaker/heated station
  • Purpose-shift arrow: 'reach the Pole & survive' → 'measure & understand the climate'
  • Modern-scientist profile cards (glaciologist, marine biologist) with what they study and how
  • Timeline from the Heroic Age (1897–1922) to present-day research stations

Teaching practices

  • Compare across clear dimensions (purpose, tools, danger, people) rather than just old-vs-new gadgets
  • Show how new tools change the QUESTIONS — from getting there to measuring and understanding the system
  • Feature diverse, contemporary scientists (e.g. Liz Thomas, Sylvia Earle) to update the image of who does polar science
  • Use paired then/now images so the contrast is immediate and concrete
  • Link to the Heroic-Age explorers topic so pupils see continuity and change, not two disconnected eras

Activities to try

  1. 1

    Then vs Now: a four-dimension comparison

    Why it works: Polar exploration did not end with the Heroic Age; it continued and changed. Better tools both reduce danger AND change the questions science can ask — from reaching a place to understanding a system.

    1. Study paired images or descriptions of a 1911 polar expedition and a present-day research station.
    2. Fill in a four-row comparison table across: PURPOSE, TECHNOLOGY, DANGER, and WHO TAKES PART.
    3. For PURPOSE, write the 1911 goal (e.g. 'reach the Pole first and survive — national glory') beside the modern goal (e.g. 'measure the ice and understand the climate').
    4. For TECHNOLOGY, list then-tools (sextant, dog teams, wooden ship, furs) beside now-tools (GPS/satellites, icebreaker, ice-core drill, heated station, aircraft).
    5. For DANGER, note the high fatality of the Heroic Age versus greatly reduced risk today, and say which modern tool most reduces a given risk.
  2. 2

    The purpose-shift arrow and the new question

    Why it works: Technology does more than make old goals safer; it opens new goals. An ice-core drill makes it possible to read many thousands of years of past climate — a question nobody could investigate with a sextant and dog sled. Because today's science depends on these tools, removing them would bring back many Heroic-Age difficulties.

    1. Draw an arrow from 'reach the Pole & survive' to 'measure & understand the climate'.
    2. Pick one modern tool (e.g. an ice-core drill or satellite) and write the NEW question it lets scientists ask that a Heroic-Age explorer could not.
    3. Explain in two or three sentences how the purpose of polar expeditions shifted, and why the technology made that shift possible.
    4. Answer the lift-the-flap prompt: 'What changed most — the tools or the question?' and justify your choice.
    5. Transfer task: imagine modern scientists suddenly lost GPS and satellites. Explain how much of today's polar work would become more like the Heroic Age again, which jobs would be hardest or most dangerous, and which would still be possible.
  3. 3

    Interview a modern polar scientist

    Why it works: Today's polar teams are international and diverse and include leading women scientists; the work is science-driven, which is a sharp contrast to the small national, all-male parties of the Heroic Age.

    1. Read or role-play a short profile/interview with a modern scientist — e.g. a glaciologist who reads climate records from ice cores, or a marine biologist studying the Southern Ocean.
    2. Write or speak three questions you would ask about what that scientist studies and how.
    3. Compare that scientist's stated mission with a Heroic-Age explorer's goal, writing one sentence on how they differ.
    4. Name at least one modern polar scientist and say what field that scientist works in.
