Learning Objectives

Indicator: 1.4.1.LI.3 - Explain ferrous and non-ferrous metals with engineering applications and state the uses of non-metallic materials.

By the end of the lesson, learners can:

Define ferrous and non-ferrous metals and distinguish between them using their iron content and key properties.
Identify at least five common ferrous metals and five common non-ferrous metals from real objects, charts, or specimens.
Match specific ferrous and non-ferrous metals to their appropriate engineering applications, justifying the choice based on properties such as strength, corrosion resistance, and conductivity.
Classify common non-metallic materials (plastics, ceramics, composites, and rubber) and state at least three engineering uses for each group.
Justify the selection of a metal or non-metallic material for a given engineering product by comparing relevant properties, demonstrating Level 2 and Level 3 reasoning.

Content standard: 1.4.1.CS.1 - 1.4.1.CS.1 Demonstrate knowledge in the use of engineering materials, tools and machines 1.4.1.LO.1 Apply health and safety to the use of tools and machines as well as use properties of metals and non-metals to select the right materials for a given application
Indicator: 1.4.1.LI.3 - Explain ferrous and non-ferrous metals with engineering applications and state the uses of non-metallic materials.
Suggested placement: Semester 2, Week 6 (Week 26 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Project-based learning: Learners are guided to use the appropriate charts or samples of items made of ferrous and non-ferrous metals to identify and fairly discuss the various types. Assist students to discuss the properties of various ferrous and non-ferrous metals using charts or real objects and present report. Learners also brainstorm to identify products made from plastics and types of plastics as well as manufacture of plastics products.

Assessment (1.4.1.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.
