Where does all the Earth’s water come from? The earth has a limited amount of water. That water keeps going around and around and around and … (well, you get the idea) in what we call the “Water Cycle”.
Learners of Grade 3 did an experiment to see the existence and movement of water. They came to know water is always in movement and is always changing states, from liquid to vapour to ice and back again. They connected the terms like evaporation, condensation and precipitation with the real life and gave examples as well.
