Factors Affecting Climate (LOWERN)Activities & Teaching Strategies
Active learning transforms abstract climate concepts into tangible experiences that stick with students. Working with maps, models, and simulations helps students visualize how latitude, elevation, and water shape real places they know. These hands-on tasks make invisible processes visible and measurable, deepening understanding beyond reading or lecture.
Learning Objectives
- 1Compare the influence of latitude on temperature and precipitation in two Canadian cities with different latitudinal positions.
- 2Analyze the moderating effect of proximity to a large body of water on the annual temperature range of a coastal Canadian city versus an inland city.
- 3Explain how elevation and relief features create distinct climate patterns in mountainous regions compared to prairie landscapes in Canada.
- 4Classify Canadian regions based on their dominant climate-influencing factors using the LOWERN acronym.

Mapping Activity: LOWERN Climate Maps
Provide blank Canada maps. Students label regions and annotate each LOWERN factor with examples and effects, using coloured pencils for latitude bands, arrows for winds and currents. Groups share one map feature with the class. Finish with a gallery walk.
Prepare & details
Explain how latitude influences temperature and precipitation patterns in Canada.
Facilitation Tip: During the Mapping Activity, provide a blank climate map of Canada and guide students to plot temperature and precipitation data points before drawing isolines.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Simulation Lab: Winds and Currents
Set up stations with fans for winds, warm/cold water trays for currents, and thermometers. Pairs blow fans over trays to observe temperature changes, record data in tables. Discuss how these mimic Labrador Current cooling versus Gulf Stream warming.
Prepare & details
Analyze the moderating effect of large bodies of water on coastal climates.
Facilitation Tip: In the Simulation Lab, provide small containers of water at different temperatures so students can track how currents transfer heat between land and water.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Comparison Chart: City Climates
Assign pairs Canadian cities like Toronto, Whitehorse, and Halifax. Research average temperatures and precipitation, create charts showing LOWERN influences. Present findings, explaining one factor per city.
Prepare & details
Differentiate the impact of elevation and relief on mountain climates versus plains.
Facilitation Tip: For the Comparison Chart, give students a template with columns for city pairs to ensure they organize their findings systematically.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Model Building: Elevation and Relief
Use layered clay or stacked books for mountains and plains. Students add moisture sources, drop cotton balls as clouds, and fan to simulate orographic lift and rain shadows. Measure 'precipitation' collected at bases.
Prepare & details
Explain how latitude influences temperature and precipitation patterns in Canada.
Facilitation Tip: When building relief models, supply cardboard, markers, and rulers so students create scale cross-sections that reflect actual elevations.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Teaching This Topic
Teach this topic by moving from the macro to the micro: start with continent-scale patterns on maps, then zoom into local scales with models and simulations. Avoid overwhelming students with all six factors at once. Use guided discovery so students uncover relationships rather than receive them as facts. Research shows that when students manipulate variables in simulations, their misconceptions about systems like ocean currents and elevation shrink significantly.
What to Expect
By the end of these activities, students will accurately explain how each LOWERN factor modifies climate in Canada. They will connect data to patterns, predict outcomes, and justify their reasoning using evidence from maps, simulations, and models. Clear explanations and labeled diagrams will show their grasp of key interactions.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Mapping Activity, watch for students who assume latitude only affects temperature and omit precipitation patterns on their maps.
What to Teach Instead
Prompt students to add a precipitation key using color coding and to write a short note linking lower evaporation rates at higher latitudes to reduced rainfall, using their plotted data points as evidence.
Common MisconceptionDuring the Simulation Lab, watch for students who assume all water bodies moderate climate equally regardless of temperature.
What to Teach Instead
Have students record temperature changes in soil above warm versus cold water containers and discuss why the Gulf Stream warms Atlantic Canada while the Labrador Current cools the coast.
Common MisconceptionDuring the Model Building activity, watch for students who believe elevation is the only factor affecting temperature and ignore relief effects like rain shadows.
What to Teach Instead
Ask students to label their models with arrows showing moist air rising and dry air descending, then predict precipitation differences using their models to test ideas.
Assessment Ideas
After the Mapping Activity, provide students with a map of Canada showing two major cities. Ask them to write one sentence for each city explaining how latitude and proximity to water contribute to their climate differences, using their completed maps as references.
During the Simulation Lab, present students with three brief descriptions of Canadian locations, each highlighting one or two dominant LOWERN factors. Ask students to identify the primary factor for each and share responses with a partner before revealing correct answers.
After the Model Building activity, pose the question: 'How would Calgary's climate change if the Rocky Mountains were removed?' Facilitate a class discussion where students use their relief models and concepts of elevation and relief to explain potential impacts on temperature and precipitation.
Extensions & Scaffolding
- Challenge: Ask students to predict how climate in Vancouver would change if the North Pacific Current reversed direction, using the Simulation Lab data for evidence.
- Scaffolding: Provide a partially completed relief model template with pre-labeled windward and leeward sides to support students who struggle with spatial reasoning.
- Deeper exploration: Have students research a Canadian city not studied in class, then create a LOWERN profile poster explaining its climate using all six factors.
Key Vocabulary
| Latitude | The distance of a place north or south of the Earth's equator, measured in degrees. Higher latitudes generally receive less direct sunlight, leading to cooler temperatures. |
| Ocean Currents | The continuous, directed movement of seawater. Currents can transport warm or cold water over long distances, significantly influencing coastal climates. |
| Elevation | The height of a place above sea level. Air temperature generally decreases as elevation increases. |
| Relief | The difference in elevation between the highest and lowest points in a particular area. Mountain ranges create relief that can cause significant differences in precipitation, such as rain shadows. |
| Near Water | Refers to the proximity of a location to a large body of water, such as an ocean or a large lake. Water moderates temperature, leading to milder climates with smaller temperature ranges. |
