Physical Geography of South America

South America’s dramatic landforms engage students through multiple senses and learning styles. Hands-on exploration of mountains, rivers, and plains helps students move beyond textbook descriptions to build lasting mental maps of diverse ecosystems.

Activity 01

• Stations Rotation
• 45 min · Small Groups

Stations Rotation: Landform Explorations

Prepare four stations with topographic maps, clay models, and videos: Andes elevation zones, Amazon layers, Pampas soils, and regional comparisons. Small groups spend 8 minutes per station, sketching features and noting climate impacts, then share findings in a class gallery walk.

Analyze how the Andes Mountains create distinct climate zones and influence human settlement.

Facilitation Tip

During Station Rotation: Landform Explorations, place tactile maps and labeled diagrams at each station so students can trace elevations and compare widths of landforms with their fingers.

What to look for

Provide students with a blank map of South America. Ask them to label the Andes Mountains, Amazon Basin, and Pampas. Then, have them draw arrows indicating prevailing winds and shade areas representing a rain shadow effect on one side of the Andes.

Activity 02

• Jigsaw
• 50 min · Small Groups

Jigsaw: Regional Experts

Assign expert groups to research one region (Andes, Amazon, Pampas) using texts and data sheets on climate and human use. Experts teach their findings to mixed home groups, who then answer key questions collaboratively on shared charts.

Explain the ecological significance of the Amazon Rainforest for global climate.

Facilitation Tip

In Jigsaw: Regional Experts, assign each small group one region and require them to prepare a two-minute presentation that includes a sketch, key fact, and real-world connection.

What to look for

Pose the question: 'How does the height of the Andes Mountains affect the climate on both its western and eastern slopes?' Have students write a short paragraph explaining the concept of a rain shadow and its impact on vegetation.

Activity 03

• Jigsaw
• 40 min · Pairs

Model Building: Cross-Section Dioramas

Pairs create layered dioramas showing Andes profiles with climate zones, Amazon understory, and Pampas fields using cardboard, paint, and labels. Discuss how landforms influence settlement during a peer critique session.

Compare the agricultural potential of the Pampas with other South American regions.

Facilitation Tip

For Model Building: Cross-Section Dioramas, provide only corrugated cardboard, paint, and string so groups focus on vertical layering and slope angles rather than decorative materials.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are advising a farming cooperative. Would you recommend they establish operations in the Amazon Basin, the Pampas, or the Andean highlands? Justify your recommendation by comparing the agricultural potential, including soil fertility and climate, of each region.'

Activity 04

• Jigsaw
• 35 min · Whole Class

Data Dive: Agricultural Comparisons

Whole class analyzes crop yield charts and satellite images comparing Pampas to Amazon and Andes. In pairs, students graph differences and predict settlement patterns, presenting to the class.

Analyze how the Andes Mountains create distinct climate zones and influence human settlement.

Facilitation Tip

During Data Dive: Agricultural Comparisons, give each student a blank climate graph template before they plot wheat yields versus rainfall to build data literacy step-by-step.

A few notes on teaching this unit

Teachers find success when they blend large-scale physical processes with local human impacts. Avoid starting with definitions; instead, let students discover elevation thresholds and wind patterns through guided mapping and modeling. Research shows that tactile and visual modeling builds spatial reasoning better than lectures alone.

Students will confidently identify and explain the Andes, Amazon Basin, and Pampas on a mental map, describe how elevation and wind shape regional climates, and compare agricultural potential across landscapes using data and models.

Watch Out for These Misconceptions

• During Station Rotation: Landform Explorations, watch for students who sketch the Andes as a single tall spike rather than a layered range.

  Have students run their fingers along the tactile map’s ridgeline, then lift the map to feel the elevation layers underneath; prompt them to trace how wind direction changes vegetation on each slope.

• During Jigsaw: Regional Experts, watch for students who describe the Amazon as uniformly wet jungle without noting rivers or threats.

  Provide each expert group with a transparent overlay of the Amazon Basin river network; ask them to mark deforestation zones and explain how river flow supports biodiversity and agriculture.

• During Data Dive: Agricultural Comparisons, watch for students who assume Pampas yields match all South American regions.

  Direct students to overlay their wheat graphs with Amazon crop data and Andes altitude limits; ask them to explain why soil depth and moisture drive the Pampas advantage.
