Air Mass Experiment and Characteristics

Mr. Weathers introduces an experiment to understand how air masses form using shoeboxes, bowls, warm water, ice, and plastic wrap. The experiment demonstrates the formation of different air masses by observing temperature and humidity changes in the boxes. The warm water box represents a maritime tropical air mass, the ice box a continental polar air mass, and the room temperature box a continental tropical air mass. The video concludes with an invitation to try the experiment at home.

What materials are required for the air mass experiment?

• Two shoeboxes, two bowls, warm water, ice tray, plastic wrap
