SHS1 Geography · Semester 1 Week 12: Rocks, Weathering, Soil and Mass Wasting

Lesson notes

Learning Objectives

Indicator: 1.1.2.LI.1 - Discuss the three types of rock, their characteristics, formational processes and their importance

By the end of the lesson, learners can:

Identify and classify the three types of rocks (igneous, sedimentary, and metamorphic) using observable characteristics from rock samples and pictures.
Describe the formational processes of each rock type, including the role of cooling, compaction, and heat or pressure.
Explain the importance of rocks to community and national development in Ghana, using at least three local examples.
Distinguish between the three rock types by comparing their texture, grain size, layering, and mineral content.
Work collaboratively in groups to present findings on rock types and their uses, demonstrating teamwork and inclusive participation.
