Climate Controls: Factors and BiomesActivities & Teaching Strategies
Active learning works for this topic because students need to see how climate factors interact in real time, not just hear about them. When they build models or compare data, they connect abstract ideas like latitude and altitude to visible changes in temperature and rainfall.
Learning Objectives
- 1Analyze the impact of latitude on average annual temperature and seasonal variations using climate data.
- 2Explain how ocean currents and proximity to large bodies of water moderate coastal climates compared to continental interiors.
- 3Compare the climate characteristics and dominant vegetation of at least three major global biomes.
- 4Predict how changes in altitude influence temperature and precipitation patterns within a mountain region.
- 5Synthesize the combined effects of latitude, water, altitude, and mountains on the distribution of biomes in Canada.

Model Building: Rain Shadow Bottle
Provide clear plastic bottles, hot water, ice cubes, and plastic wrap. Students heat one side to create 'moist air,' cool the other with ice to simulate mountains, and observe 'rain' forming on one side only. Groups record differences and draw side-view diagrams. Discuss links to real biomes.
Prepare & details
Explain why proximity to water drastically changes a region's climate.
Facilitation Tip: During the Rain Shadow Bottle activity, circulate to ensure students are adding water slowly enough to see the condensation form on the cold side of the bottle.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Mapping Activity: Global Climate Factors
Distribute blank world maps. Students mark latitudes, oceans, mountains, and major currents, then shade biome types using color codes. Pairs add labels explaining one factor per region, like coastal moderation in Europe. Share maps in a gallery walk.
Prepare & details
Analyze how mountain ranges create rain shadows and diverse ecosystems.
Facilitation Tip: For the Global Climate Factors mapping, provide colored pencils and a legend key so students can mark ocean currents, altitude, and latitude with consistent symbols.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Data Comparison: Coastal vs Inland Climates
Supply temperature and precipitation graphs for paired cities, such as Toronto and Winnipeg. Students in small groups chart differences, identify controlling factors, and predict biome types. Present findings with evidence from graphs.
Prepare & details
Predict how shifting climate patterns are altering the boundaries of global biomes.
Facilitation Tip: When comparing coastal and inland climates, assign specific cities to each pair so comparisons are systematic and not random.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Simulation Game: Biome Shifts
Use cards showing climate changes like warmer winters. Whole class sorts biome species into new regions on a large map, debating factors like rain shadows. Vote on predictions and justify with prior models.
Prepare & details
Explain why proximity to water drastically changes a region's climate.
Facilitation Tip: In the Biome Shifts simulation, remind groups to record the climate factor they changed and the biome that resulted before testing another change.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Teaching This Topic
Teachers should begin with a local example students can relate to, like comparing a nearby coastal city to an inland one. Avoid starting with global examples, as students need to anchor new ideas in familiar contexts first. Research shows students grasp climate controls better when they manipulate variables in hands-on models rather than just viewing static images or listening to lectures.
What to Expect
Students will explain how latitude, water, altitude, and mountains shape climate and biomes. They should use evidence from their models, maps, and data to justify why two places at the same latitude can have different climates, and how these controls lead to biome boundaries.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Mapping Activity: Global Climate Factors, watch for students who assume all coordinates at the same latitude have identical climates.
What to Teach Instead
Ask students to compare climate graphs for two cities at the same latitude but different proximities to water, then discuss how the proximity to water changes the temperature range and precipitation patterns.
Common MisconceptionDuring the Model Building: Rain Shadow Bottle activity, watch for students who believe mountains cause rain on both sides equally.
What to Teach Instead
Have students observe which side of the bottle collects condensation and which side stays dry, then relate this to the windward and leeward sides of a mountain range.
Common MisconceptionDuring the Simulation Game: Biome Shifts, watch for students who think biome boundaries are fixed and never change.
What to Teach Instead
Encourage students to test what happens when they adjust temperature or precipitation sliders, recording how the biome shifts to reinforce the idea of dynamic boundaries.
Assessment Ideas
After the Mapping Activity: Global Climate Factors, ask students to identify two Canadian cities on a map and explain how two climate controls (e.g., latitude, water proximity) influence their respective biomes.
After the Data Comparison: Coastal vs Inland Climates activity, pose the question: 'Which climate control factor would you prioritize if building a city in an area with extreme temperatures, and why?' Facilitate a discussion where students justify their choices using data from their comparisons.
During the Simulation Game: Biome Shifts, give each student a biome card and ask them to write one climate factor that supports its existence and one real-world location where it is found.
Extensions & Scaffolding
- Challenge: Ask students to design a new biome based on a combination of climate controls not currently found on Earth, then present their biome and explain its characteristics.
- Scaffolding: Provide sentence starters for the mapping activity, such as 'The ocean current near [location] is ___, which makes the climate ___ because ___.'
- Deeper exploration: Have students research how human activities like deforestation or urbanization alter one of the climate controls they studied, then present findings on climate impact.
Key Vocabulary
| Latitude | The distance of a place north or south of the Earth's equator, measured in degrees. It significantly affects the amount of solar energy received. |
| Altitude | The height of a place above sea level. Higher altitudes generally experience cooler temperatures. |
| Rain Shadow | A dry area on the leeward side of a mountain range, where moist air has lost its moisture on the windward side. |
| Biome | A large geographical area characterized by specific plant and animal communities adapted to its climate, such as tundra, forest, or grassland. |
| Ocean Currents | Continuous, directed movements of seawater. They transport heat, influencing the climate of coastal regions. |
