Learning Objectives

Indicator: 3.2.3.LI.4 - Design and construct energy management systems solutions for lighting and consumer appliances.

By the end of the lesson, learners can:

Identify at least three energy management system solutions applicable to lighting and consumer appliances in their school or home.
Design a simple energy management system for a specified lighting or consumer appliance, showing the components and their connections.
Construct a working prototype of an energy management device using available electrical and electronic components.
Test and evaluate the performance of their constructed device against set energy-saving criteria.
Present and defend their group project to the class, explaining how their design conserves energy.
