Reading Landform Maps and Models

Grade 4 Earth Science — Shaping Earth’s Surface | Unit 1, Lesson 4 of 6

📚 Grade: 4th Grade⏱️ Duration: 45–60 minutes🔬 Subject: Earth Science — Shaping Earth’s Surface
🗺️⛰️🔍
Maps and models help scientists compare landforms and infer how Earth’s surface may have changed.
📋 NGSS Standard:
4-ESS2-1 — Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation. / 4-ESS2-2 — Analyze and interpret data from maps to describe patterns of Earth’s features.

🎯 Learning Objective

Students will use maps and models as evidence to compare landforms and infer how Earth processes shaped them.

💡 The Big Idea

Scientists use maps, cross-sections, and models to make large Earth-surface patterns easier to study and explain.

🔬 The Science

Representations help us see land patterns that would be hard to compare from ground level alone.

What is happening?

Landform maps and models make large-scale Earth features easier to compare. They can show where hills, valleys, rivers, deltas, and floodplains are located and how they connect.

Why it works that way

These representations are powerful because they reduce complexity while keeping the pattern. Elevation, contour, color, and symbols can all help scientists infer how water and sediment move across a place.

Look for this in the lesson

Students should practice using a model as evidence, not decoration. The real scientific work is reading clues from it and connecting those clues to Earth processes.

Ask while you read: What does the map or model help you notice that might be hard to see from one spot on the ground?

📋 Printables

🧪 Investigation

Step 1 — Study a landform map (10 min)
Look for high places, low places, valleys, river paths, and possible places where water collects.
Step 2 — Compare map and model (10 min)
Use a physical model or drawing to show how the map represents shape from above.
Step 3 — Make evidence-based inferences (10 min)
Students use the map to explain where erosion or deposition might happen.
Step 4 — Label patterns (10 min)
Mark likely slopes, flatter places, and paths water might follow.
Step 5 — Defend one claim (10 min)
Students write a claim about the landscape and support it with at least two pieces of evidence from the representation.

💬 Discussion Questions

Why do scientists use maps and models?They make big systems easier to study and explain.
What can a map show that a photo might not show clearly?Patterns of location, slope, pathways, and relationships across the whole area.
How can a model help explain erosion?It can show where water might move faster on a slope and where material may collect.
What counts as evidence from a map?Features you can point to on the map, such as river paths, lower areas, or steep slopes.

🚀 Extensions

Extension: Build a quick hill-and-valley model from clay or towels and compare the model to a simple overhead sketch.

👩‍🏫 Parent/Teacher Notes

Teaching move: Encourage students to point to exact map features instead of making vague claims.

Misconception to catch: A model is not supposed to copy every detail. It is meant to highlight important relationships.

Student Worksheet

Name: ________________________     Date: ________________________

Use map evidence to explain a landform pattern

Look closely at the map or model and support your claim with evidence.

Feature on the map/modelWhat does it suggest?Why?

2️⃣ Write one claim with evidence

🔑 PARENT ANSWER KEY — Detach before giving worksheet to students

Sample ideas

A student might claim that erosion is likely strongest on a steep slope because the map shows a narrow valley and water path leading downhill.
