Wind: What it is and What it DoesActivities & Teaching Strategies
Active learning helps first-year students connect abstract concepts like air pressure differences to concrete, observable experiences. Hands-on activities like building tools and testing models make invisible forces visible and memorable.
Learning Objectives
- 1Explain the cause of wind as a result of uneven heating and pressure differences.
- 2Identify at least three observable indicators of wind speed and direction.
- 3Evaluate the positive and negative impacts of wind on the local environment.
- 4Design and construct a simple device to measure wind speed.

Pairs: Pinwheel Testing
Pairs cut and assemble paper pinwheels using straws, pins, and tape. They take turns holding them in natural wind or from a fan, noting spin speed and direction. Discuss how pinwheel movement shows wind strength.
Prepare & details
What makes the wind blow?
Facilitation Tip: During Pinwheel Testing, circulate and ask pairs to predict which pinwheel will spin fastest based on its placement relative to the fan.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Small Groups: Anemometer Build
Groups use plastic cups, dowels, and string to construct simple anemometers. Spin them in wind, count rotations per minute, and compare group data on a class chart. Relate findings to Beaufort scale levels.
Prepare & details
How can we tell if it's windy?
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Whole Class: Beaufort Scale Demo
Display images or videos of Beaufort levels from 0 to 12. Class observes a fan at varying speeds, mimicking effects like leaf movement or paper flying. Vote and record matches to the scale.
Prepare & details
What are some good and bad things about wind?
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Individual: Wind Effects Hunt
Students walk school grounds noting wind effects: good like drying clothes, bad like fallen branches. Sketch or photo five examples, then share in plenary to categorize impacts.

Teaching This Topic
Teach wind as a dynamic system by starting with students’ lived experiences, then layering tools and data. Avoid over-simplifying; use misconceptions as springboards for investigations. Research shows that combining movement, measurement, and discussion deepens understanding of invisible forces like wind.
What to Expect
Students will explain wind’s cause using pressure differences, measure its strength with tools, and identify both positive and negative effects in their environment. Successful learning includes accurate use of terms and tools during activities.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring Pinwheel Testing, watch for students who believe trees create wind.
What to Teach Instead
Use a fan and pinwheels to demonstrate that moving air causes objects to spin. Ask students to observe what happens when the fan is off and then on.
Common MisconceptionDuring Wind Effects Hunt, watch for students who label all wind effects as harmful.
What to Teach Instead
Provide a chart with columns for positive, negative, and neutral effects. Guide students to categorize each observation they record.
Common MisconceptionDuring Anemometer Build, watch for students who assume wind always blows the same way.
What to Teach Instead
Have students place anemometers in different locations around the room and compare readings. Ask them to mark wind direction with arrows on a class map.
Assessment Ideas
After Beaufort Scale Demo, ask students to draw a simple diagram showing wind moving from a high-pressure area to a low-pressure area. Have them include arrows and one sentence explaining the pressure difference causes the wind.
During Pinwheel Testing, pause after two minutes and ask students to list two indicators of wind they observed (e.g., pinwheel spinning, hair moving). Call on students to share aloud.
After Wind Effects Hunt, facilitate a class discussion using the prompt: 'Imagine you are designing a new park. What are two ways you would use wind to your advantage and two ways you would protect the park from strong winds?' Have students share responses in pairs before whole-group sharing.
Extensions & Scaffolding
- Challenge students to design a wind-powered vehicle using recycled materials after Anemometer Build.
- Scaffolding: Provide sentence stems for Wind Effects Hunt, such as 'I see wind moving ______ by ______.'
- Deeper exploration: Have students research how wind turbines work and present findings to the class.
Key Vocabulary
| Air Pressure | The force exerted by the weight of air in the atmosphere. Differences in air pressure cause air to move. |
| Wind Vane | A tool used to show the direction from which the wind is blowing. It typically has a pointer that aligns with the wind. |
| Anemometer | An instrument used to measure wind speed. Common types include cup anemometers that spin in the wind. |
| Erosion | The process by which wind, water, or other natural agents wear away land. Wind erosion can move soil and sand. |
