Lesson notes

Learning Objectives

Indicator: 2.3.3.LI.2 - Analyse the effects that manufacturing activities have on the environment (e.g., the effects of waste disposal, power consumption, destruction of the environment)

By the end of the lesson, learners can:

Identify at least three types of manufacturing waste and explain how each affects the environment.
Describe how power consumption in manufacturing contributes to environmental degradation, including the role of fossil fuels and energy efficiency.
Analyse at least two examples of environmental destruction caused by manufacturing activities in Ghana and propose a mitigation measure for each.
Categorise manufacturing environmental effects as either positive or negative based on a given scenario.
Evaluate the waste management practices of a local manufacturing industry and relate them to environmental safety using evidence from a field visit or case study.
