Activity 01
Demonstration: Cloud in a Jar
Fill a jar with hot water, add a few drops of food colouring, then place a cold metal lid on top with ice. Observe condensation forming on the lid and drips falling as precipitation. Discuss how pressure changes mimic atmospheric lift. Groups record sketches and measurements.
Explain the conditions necessary for cloud formation and precipitation.
Facilitation TipDuring the Cloud in a Jar demonstration, emphasize the role of temperature change by slowly adding ice to the jar to show condensation forming on the sides.
What to look forPresent students with images of different cloud types. Ask them to label each cloud and write one sentence explaining the atmospheric conditions that likely led to its formation.
