Climate Regions and Conditions

Earth Science — Weather & Climate | Unit 1, Lesson 2 of 6

📚 Grade: 3rd Grade⏱️ Duration: 45–60 minutes🔬 Subject: Earth Science — Weather & Climate
🌍☀️❄️🌴
Climate describes the usual weather conditions in a place over a long time.
📋 NGSS Standard:
3-ESS2-1 — Obtain and combine information to describe climates in different regions of the world.

🎯 Learning Objective

Students will compare different climate regions and explain how climate is different from daily weather.

💡 The Big Idea

Weather tells us what it is like right now. Climate tells us the usual pattern of weather in a place over a long time.

🔬 The Science

Climate is the bigger long-term pattern that helps describe what a region is usually like.

What is happening?

Climate describes the usual weather conditions of a place over a long time. Different regions can have different typical temperatures, rainfall amounts, winds, and seasons because of location, elevation, and nearby water.

Why it works that way

Weather changes day to day, but climate is the longer-term pattern. That is why a hot day in a cool climate or a rainy day in a dry climate does not automatically change the climate classification.

Look for this in the lesson

Students should compare “today’s weather” with “what it is usually like here.” That distinction is the heart of understanding climate regions.

Ask while you read: How is climate different from today’s weather report?

🌍 Climate Cards for This Lesson

Use these four climate cards during the region-comparison activity. Each card shows the usual conditions in that region over time, not just the weather on one day.

Real-life desert environment with dry ground and sparse plants.
Desert
Real-life rainforest environment with dense green plants and wet leaves.
Rainforest
Real-life tundra environment with snow, ice, and low plants.
Tundra
Real-life temperate region with trees, grass, and mild conditions.
Temperate Region
☀️
Desert
Hot + Dry

Usual conditions
A desert environment is usually very dry. Many deserts are hot during the day and get very little rain over time.

What you might expect

  • Dry sand or rocky ground
  • Very few puddles, streams, or wet places
  • Plants and animals that can live with little water
🌧️
Rainforest
Warm + Rainy

Usual conditions
A rainforest environment is usually warm, wet, and rainy. It gets a lot of precipitation over time.

What you might expect

  • Lots of green plants and tall trees
  • Wet ground, puddles, or dripping leaves
  • Air that often feels damp or humid
❄️
Tundra
Very Cold

Usual conditions
A tundra environment is usually very cold for much of the year. The ground can stay frozen, and there are very short growing seasons.

What you might expect

  • Snow, ice, or frozen ground
  • Very short grasses, mosses, or small plants
  • Animals with thick fur or other ways to stay warm
🍂
Temperate Region
Mild + Seasonal

Usual conditions
A temperate environment usually has moderate temperatures and seasons. It is not extremely hot, extremely cold, or extremely dry all year.

What you might expect

  • Weather that changes with the seasons
  • Trees that may bloom in spring or lose leaves in fall
  • Rain or snow at different times of year
What to notice: Each card describes a long-term pattern. A single cold day in a temperate region or a rainy day in a desert does not change the climate by itself.

Let's Get Started

Step 1 — Review weather from Lesson 1 (5 min)
Ask: “What could change tomorrow?” to remind students weather is short-term.
Step 2 — Introduce four climate regions (10 min)
Use the included climate cards and real-life climate scenes on this lesson page to compare a hot dry desert, a rainy rainforest, a cold tundra, and a temperate region.
Make it hands-on: As you look at each region, have your child point and say what they notice first, like sand, puddles, snow, trees, cactus, or ice. Then ask, "Would this place usually feel hot, cold, wet, or dry?"

Quick clothing challenge: Give your child 25 seconds to find something around the house that would help in one climate. For example, a sun hat or sunscreen for the desert, an umbrella or rain boots for the rainforest, gloves or a scarf for the tundra, or a light sweater and sandals for a temperate region. Let them explain their choice, then applaud their creativity.
Step 3 — Compare regions on the worksheet (10 min)
Go to Question 1 on the worksheet first. Use the included climate cards to fill in the chart about usual conditions and what your child might expect in each region.
Step 4 — Sort examples into weather or climate (10 min)
Now move to Question 2 on the worksheet. Read each statement out loud and ask: "Is this happening right now, or is this something that is usual over time?" Use the climate cards to help teach the difference as you go.
Step 5 — Write a contrast statement (10 min)
Students complete a sentence that clearly distinguishes weather from climate.

Discussion Questions

How is climate different from weather?Weather is short-term; climate is the usual long-term pattern.
Why can two places have different climates?Different regions have different usual temperatures and precipitation patterns, so the land, plants, animals, and clothing that fit those places can be different too.
Can a cold day happen in a warm climate?Yes, one day of weather does not change the whole climate.
Why do scientists use the word “usual” when talking about climate?Climate is about what is common over time, not one event.

Extensions

Extension: Choose one climate region and draw what clothing, plants, or homes might fit its usual conditions.

Another extension: Pick two climate regions and make a fast compare-and-contrast poster. Add one box for usual conditions, one box for plants and animals, and one box for what a person might wear in each place.

Parent/Teacher Notes

Teaching move: Keep repeating the contrast: weather = right now, climate = usual pattern over time.

Important misconception to catch: Students may think one rainy day means a place has a rainy climate. Bring them back to “usual over time.”

1️⃣ Compare Climate Regions — Sample Acceptable Answers

Students should use the included climate cards from this lesson page as their evidence source.

Desert: usually hot and dry, with very little rain over time. Rainforest: usually warm and rainy. Tundra: usually very cold for much of the year. Temperate: moderate conditions with seasons.

2️⃣ Weather or Climate? — Answer Key

“It is raining today.” = weather. “This place is usually hot and dry.” = climate. “The winter here is often snowy.” = climate. “The sky is cloudy this morning.” = weather.

3️⃣ Explain the Difference — Sample Response

“Weather is what it is like right now, but climate is the usual weather pattern in a place over a long time.”
