The scientific process called condensation forms droplets on a cold glass. When warm air with water vapour touches the cold surface, the vapour cools down and changes back into liquid water. These droplets are not from the glass itself but from the air. This process helps us understand how clouds and rain form in nature as part of the water cycle.

Two state changes are observed: first, melting—where solid ice turns into liquid water due to heat; and second, evaporation—where liquid water becomes steam or vapour when boiled. These experiments show that water can change between solid, liquid and gas forms with temperature changes. Such changesRead more

Heating water in sunlight causes it to evaporate slowly, meaning it changes from liquid to gas. This invisible gas is called water vapour. The process, known as evaporation, helps us understand how water rises from oceans, rivers and puddles to form clouds. It’s an important step in the water cycleRead more
Heating water in sunlight causes it to evaporate slowly, meaning it changes from liquid to gas. This invisible gas is called water vapour. The process, known as evaporation, helps us understand how water rises from oceans, rivers and puddles to form clouds. It’s an important step in the water cycle and shows how sunlight powers the natural movement of water on Earth.

In the sealed plastic bag, coloured water heats up from sunlight and turns into vapour. This vapour rises, cools and forms small droplets on the inner side of the plastic—showing condensation. These droplets eventually fall, showing precipitation. This activity models the water cycle with evaporation, condensation and rainfall inside a bag. It helps us understand how weather forms and water moves in nature.

Sunlight plays a key role in the water cycle. It heats rivers, lakes and oceans, causing water to evaporate into vapour. This vapour rises, cools and forms clouds. Eventually, it returns as rain or snow. Without sunlight, the cycle wouldn’t begin and water would not move through air, land and sky. SRead more
Sunlight plays a key role in the water cycle. It heats rivers, lakes and oceans, causing water to evaporate into vapour. This vapour rises, cools and forms clouds. Eventually, it returns as rain or snow. Without sunlight, the cycle wouldn’t begin and water would not move through air, land and sky. Sunlight helps renew freshwater sources and supports all life on Earth.
