SHS3 Manufacturing Engineering · Semester 1 Week 3: Classification of Materials

Lesson notes

Learning Objectives

Indicator: 3.1.1.LI.3 - State the applications of semi-conductors, biomaterials, smart materials and nanomaterials.

By the end of the lesson, learners can:

State at least three industrial applications of semiconductors, with reference to everyday devices they encounter in Ghana.
Name at least three uses of biomaterials in manufacturing, including healthcare and packaging.
Describe at least three applications of smart materials, giving an example of a product that responds to a change in its environment.
Identify at least three applications of nanomaterials in manufacturing, such as in coatings, textiles and medicine.
Classify given products or scenarios under the correct advanced material category (semiconductor, biomaterial, smart material or nanomaterial) and justify their classification.

These objectives build on Week 1 (importance of advanced materials) and Week 2 (structure of semiconductors), and they prepare learners for Week 5 and 6, where they will study bamboo as a separate engineering material.

Exemplars (from the NaCCA curriculum)

Research-Based Learning: Put learners in mixed-ability groups and let them research and make presentations on biomaterials, smart materials, nanomaterials, and their applications. Let learners provide feedback
Project-Based Learning: Let students in mixed-ability groups identify a problem in the school, use smart materials to develop a solution to the problem, and present their results to the class for feedback.
Teaching and Learning Materials:
- * Videos on the application of semiconductors
- Biomaterials
- Smart materials
- * Nanomaterials * Textbooks
- * Library resources * Internet access
- * Projector * Audio-visuals
Assessment (3.1.1.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.
