Water inside the bag heats up and turns into vapour. The vapour cools and forms droplets on the inner cover. This shows evaporation and condensation, just like in the real water cycle. Class 5 NCERT EVS Our Wondrous World Chapter 1 ...
When water is heated in sunlight, it slowly disappears as vapour. This process is called evaporation. It shows how heat turns water into gas, just like it happens in the water cycle. Class 5 NCERT EVS Our Wondrous World Chapter 1 ...
When ice melts, it changes from solid to liquid. When water boils, it becomes vapour. These activities show how water changes its form due to heat—called melting and evaporation. Class 5 Our Wondrous World – The World Around Us – Chapter ...
Condensation causes water droplets to form on a cold glass. Water vapour from warm air touches the cold surface, cools down, and turns back into liquid droplets on the outside of the glass. Class 5 Our Wondrous World – The World ...
