Lesson Summary:
The lesson introduces the children to the water cycle. The discussion is designed to be read by the children, either as a paired reading activity or with the assistance of the teacher, depending on their reading skills. The teacher could use a kettle to demonstrate the processes of evaporation and condensation. Activity A helps the children to visualize the processes described and Activity B gives them the opportunity to describe the water cycle as part of an imaginative exercise.
Objectives:
- The children will be able to describe the water cycle.
- The children will understand the vocabulary used to explain the processes of the water cycle.
Subject Area:
Science
Lesson Excerpt:
Where does rain come from? Well, from the clouds, of course, but how does it get there? and where does it go to, once it’s fallen? Let’s find out.
Did you know that 71% of the earth in covered with water? That is more than twice as much water as there is land. That sounds like a lot of water but how does it get up into the clouds? By a process called evaporation. Evaporation happens when the sun heats the water in the rivers, lakes or oceans and turns it into water vapour which rises up into the air. Plants lose water through their leaves, this is called transpiration (when we lose water it’s called sweat!). This process also puts water vapour back into the air.
