B6 Science · Term 1 Week 7: Earth Science

Lesson notes

Learning Objectives

Indicator: B6.2.1.2.1 - Explain how rain falls from clouds

By the end of the lesson, learners can:

Describe the processes of evaporation, condensation, dew point, and precipitation in their own words.
Explain the role of tiny dust or smoke particles in the formation of raindrops within a cloud.
Demonstrate how gravity causes water droplets to fall from clouds as rain.
Construct a simple model or diagram showing how raindrops form and fall from the high parts of a cloud.
State reasons why not all clouds produce rainfall.
