About the Talking About Clouds Lesson
This lesson covers the way in which clouds are formed. Activity A reinforces the information given in the lesson. Activity B gives the children the opportunity to identify and describe the three main cloud formations.
• The children will be able to identify cloud formations.
• The children will be able to demonstrate their understanding of how clouds are formed.
The air is full of invisible, floating water droplets called water vapor. These droplets have evaporated from rivers, lakes and the sea. The heat of the sun warms the moisture-laden air and causes it to rise. When the air cools, the water vapor condenses, collecting around tiny particles of dust in the air. It then becomes visible as a cloud. As more and more water droplets or ice crystals are formed, they become heavy and fall to the earth as rain, hail or snow. We call this precipitation.
