SHS1 Manufacturing Engineering · Semester 1 Week 3: Classification of materials

Lesson notes

Learning Objectives

Indicator: 1.1.1.LI.2 - Group materials based on their applications i.e., clothing, building, food, automobiles, electronic, medical.

By the end of the lesson, learners can:

Sort at least 15 common materials into the correct industry category (clothing, building, automobile, food processing, electronic, or medical) with at least 80% accuracy.
Identify the specific materials used to produce given components in at least three different industries and explain why those materials are suitable for that application.
Construct a concept map or webbing diagram showing the relationships between industries, components, and the materials used to produce them.
Justify material choices for a given application by stating at least one performance requirement the material must meet.
Work collaboratively in pairs and groups, demonstrating respect and tolerance for peers’ contributions and critiques during classification activities.

Exemplars (from the NaCCA curriculum)

Talk for Learning: Learners think-pair-share and group components according to their application in the clothing, building, automobile, food processing and electronic industries and identify the materials used in producing the components in the various industries such as:
- Clothing Industry: Cotton, wool, silk, leather, fibers etc.
- Building Industry: Wood, earth, cement, steel, plastic, stone, glass, bamboo, carbon fibre, straw etc.
- Automobile Industry: Steel, rubber, plastics, aluminium etc.
- Food processing industry: Raw materials (fish, nuts, fruits, vegetables etc.), stainless steel, plastics, paper, glass, aluminium etc. Electronic Industry: Semi-conductors, Medical Industry: Biomaterials Structure contributions of pairs using webbing or concept maps. Encourage learners to respect and tolerate others' contributions and critiques.
