SHS2 Engineering · Semester 2 Week 10: Energy Efficiency and Conservation

Lesson notes

Learning Objectives

Indicator: 2.2.3.LI.4 - Identify appropriate energy-saving tips for thermal equipment.

By the end of the lesson, learners can:

Define thermal equipment and list at least five common examples found in homes, schools, and industries in Ghana.
Identify at least six practical energy-saving tips for thermal equipment such as boilers, ovens, water heaters, and air conditioners.
Explain the principle behind at least three energy-saving measures for thermal equipment (for example, insulation, maintenance, and temperature control).
Compare energy-saving tips for thermal equipment with those for electrical equipment covered in Week 9 and explain how they differ.
Conduct a simple assessment of thermal equipment in the school environment and recommend appropriate energy-saving measures based on their findings.

Exemplars (from the NaCCA curriculum)

Managing Talk for Learning: In a moderated discussion, learners discuss energy conservation measures for thermal equipment. Furthermore, learners compare varied measures to achieve common saving goals in various equipment and systems.
Experiential Learning: Learners watch videos on energy savings in thermal equipment.
Problem-based, Experiential and Collaborative Learning: In groups, learners assess facilities in the school to know the energy-saving measures in place and those that could be deployed. The groups present their findings to the class.

Assessment (2.2.3.AS.4). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.
