Antarctica Reading Comprehension Passage

Lesson Snapshot
• Title: Antarctica
• Genre: Nonfiction (informational passage)
• Subject: Science / Geography (Polar environments; exploration & research)
• Primary Topic: Exploration, South Pole, treaty, and ice core science
• Estimated Guided Reading Level (A–Z): S
• Support pages noted in the PDF: visualization and pre-reading trivia (pp. 1–2), mixed questions (p. 4), vocabulary activities (p. 5), creative writing (p. 6), extension activities + summary box (p. 7), answer key (p. 8).
• Support-page QA notes: The vocabulary activity includes “Expedition,” which does not appear in the passage; one mixed question asks why compasses “spin strangely,” which the passage does not explain.

What This Lesson Teaches Best
• How Antarctica went from a blank spot on maps to a confirmed icy continent described by explorers.
• Key physical features of the continent: cold, dry, windy conditions; little inland snow; land “high above sea level” like a “frozen plateau.”
• A short exploration timeline using dates and evidence (1820 reports of ice shelves; 1895 people stepped onto the continent).
• How journeys toward the South Pole were described (sleds, dogs, strange compasses) and what happened in December 1911 and afterward.
• Why international science cooperation matters there, including the International Geophysical Year, the Antarctic Treaty, and what ice cores can reveal through layers.

Learning Goals
• Students will describe why early mapmakers could not point to land far south “with certainty.”
• Students will identify details that describe Antarctica’s inland climate and land shape (dry, windy, little snow; “frozen plateau”).
• Students will retell key events from the passage’s timeline using dates (1820, 1895, 1911, 1959).
• Students will explain what ships reported seeing in 1820 and how the author describes the coastal environment.
• Students will describe what happened when Roald Amundsen reached the South Pole and what Robert Falcon Scott found later.
• Students will explain what the passage says nations promised in 1959 and why ice cores are compared to a “frozen calendar.”

Key Vocabulary From the Text
• certainty — being sure something is true.
