Activity 01
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.
What makes the wind blow?
Facilitation TipDuring Pinwheel Testing, circulate and ask pairs to predict which pinwheel will spin fastest based on its placement relative to the fan.
What to look forOn an index card, students will draw a simple diagram showing a high-pressure area and a low-pressure area. They will add arrows to show wind direction and write one sentence explaining why the wind blows.
