Activity 01
Globe Demo: Cell Formation
Place a globe under a heat lamp at the equator, add incense smoke to visualize rising air. Rotate the globe slowly to show Coriolis deflection. Groups sketch predicted cell boundaries and compare to real patterns.
Explain the Hadley, Ferrel, and Polar cells and their influence on global climate.
Facilitation TipDuring Globe Demo: Cell Formation, emphasize slow, deliberate hand movements to show air rising and sinking along the globe’s curve, matching the Hadley, Ferrel, and Polar cells.
What to look forProvide students with a world map showing major pressure systems and wind patterns. Ask them to label one example of a Hadley, Ferrel, and Polar cell, and identify one type of weather associated with a high-pressure system and one with a low-pressure system.
