Activity 01
Demo: Convection Box Model
Build a transparent box with a heat source under one end and coloured smoke or incense to visualise air currents. Students observe rising warm air and sinking cool air, then sketch the circulation pattern. Discuss how this scales to global cells.
Explain how differential heating of the Earth's surface drives atmospheric circulation.
Facilitation TipDuring the Convection Box Model demo, emphasize the color change of the water as a visible proxy for temperature and density differences.
What to look forOn one side of an index card, students will draw a simplified diagram of either a high-pressure or low-pressure system, labeling the direction of air movement. On the other side, they will write one sentence describing the typical weather associated with their chosen system.
