Hemisphere Hunt Slides Grade 4 Geography Expedition
Lesson 1 • Continent Quest
Global Navigation
Continent on the Map
Where in the world is North America? Discover our home continent's hemispheres, bordering oceans, and global neighborhood.
2 Hemispheres
Northern & Western
3 Giant Oceans
Pacific, Atlantic, Arctic
3rd Largest
Continent on Earth
01
Earth's Four Hemispheres
Global Coordinates
Latitude Divider
Northern Hemisphere
The Equator cuts Earth into North and South. North America sits entirely north of the Equator .
Every part of North America has north latitude!
Longitude Divider
Western Hemisphere
The Prime Meridian divides East and West. North America sits almost entirely in the Western Hemisphere .
Located west of the Atlantic Ocean!
Geographer's Rule: When someone asks for North America's global address, remember: North and West!
02
Surrounded by Water: Three Oceans
Ocean Boundaries
Arctic Ocean
To the North
Icy, cold waters touch northern Canada, Alaska, and Greenland. Frozen sea ice covers much of it year-round.
Home to polar bears & narwhals
Atlantic Ocean
To the East
Stretches between eastern North America, Europe, and Africa. Carries busy shipping lanes and the Gulf of Mexico.
Borders eastern Canada & the U.S.
Pacific Ocean
To the West
The largest, deepest ocean on Earth. Borders the western shores of Canada, the United States, and Mexico.
Part of the volcanic "Ring of Fire"
Water forms natural boundaries on three sides of North America!
03
Continental Gateways
Connections & Straits
Southern Gateway
Isthmus of Panama
A narrow strip of land connecting Central America (the southern tip of North America) directly to South America.
Key Fact: The famous Panama Canal cuts across this isthmus, linking the Atlantic and Pacific!
Northwestern Gateway
Bering Strait
A narrow body of water separating Alaska (North America) from Russia (Asia). At its narrowest, it is only 55 miles wide.
Key Fact: Thousands of years ago, an ancient ice bridge connected the two continents here!
Total Land Area: About 9.5 million square miles!
Only Asia and Africa are larger

Geographer's Think Box Rubric & Sample (4 pts)
Open Response
Exemplar Student Response (Full Credit - 4 pts):
"North America is in the Northern Hemisphere because it is located entirely north of the Equator. It is also in the Western Hemisphere because it lies west of the Prime Meridian."
Full Credit (4 pts): Mentions both hemispheres correctly and references at least one divider line (Equator / Prime Meridian) in complete sentences.
Partial Credit (2-3 pts): States Northern and Western correctly but forgets divider lines or writes incomplete sentences.
Common 4th Grade Misconception: Students often think Central America and Greenland are separate continents. Emphasize that Greenland and Central American nations are part of the North American continent!

Land of Wonders
From towering snowcapped peaks and endless prairies to mighty freshwater seas and deep red canyons—explore the natural marvels of North America!
2 Major Ranges
Rockies & Appalachians
5 Great Lakes
20% of Earth's Fresh Water
Great Plains
Vast Continental Heartland
01
Two Mountain Spines: West vs. East
Continental Elevators
Western Giant
The Rocky Mountains
Stretches over 3,000 miles from northern British Columbia (Canada) all the way to New Mexico (USA).
Features:
Jagged, snow-capped peaks rising over 14,000 feet. Home to grizzly bears, bighorn sheep, and the Continental Divide!
Eastern Ancient
The Appalachian Mountains
Stretches over 1,500 miles from eastern Canada down to central Alabama in the United States.
Features:
Much older than the Rockies! Weathering and erosion have rounded their summits into lush, green, rolling tree-covered ridges.
The Continental Divide in the Rockies decides which ocean river water flows into!
Pacific vs. Atlantic
02
The Heartland: Plains & River Basin
Center of North America
Vast Grasslands
The Great Plains
A massive expanse of flat prairies and gently rolling grasslands spreading between the Mississippi River and the Rocky Mountains.
Known as "America's Breadbasket" for producing wheat, corn, and grain. Historic grazing lands of giant bison herds!
Mighty Waterway
The Mississippi River
Flows over 2,340 miles from Lake Itasca in Minnesota down into the warm Gulf of Mexico in Louisiana.
Along with its Missouri and Ohio tributaries, it creates one of the world's most productive river transportation networks!
Geography Connection: Water flowing from both the Rockies and the Appalachians empties into the Mississippi river system!

Freshwater Seas & Carved Canyons
Natural Marvels
Freshwater Giant
The 5 Great Lakes
Superior, Michigan, Huron, Erie, and Ontario. Remember the acronym H-O-M-E-S !
