Objectives

Introducing and Classifying Materials (1h)

 
  1. State that materials can be classified into groups according to similarities in 1
their microstructures and properties.
    2.  
  2. Explain that several classifications are recognized but that no single 3
classification is “perfect”.
  3. State that, for this course, materials are classified into groups: timber, 1
metals, ceramics, plastics, textile fibres, food and composites and that some
of these groups have subdivisions.
Properties of Materials (4h)
Physical Properties
  1. Define the physical properties of density, electrical resistivity, thermal 1
conductivity, thermal expansion and hardness.
  2. Explain a design context where each of the properties in 3.2.1 is an 3
important consideration.
  3. Mechanical Properties
  4. Define the mechanical properties of tensile strength, stiffness, toughness 1
and ductility.

  5. Explain a design context where each of the properties in 3.2.3 is an 3
important consideration.
Aesthetic characteristics
  1. Outline the characteristics of taste, smell, appearance, texture and colour.
  2. Explain a design context where each of the characteristics in 3.2.5 is an 3
important consideration.

3.3 The IB Properties/Materials Matrix (1h)

  1. Explain how all the groups and sub-groups specified in 3.1 can be 3
organized into a properties/materials matrix
  2. Explain the relative values of the properties in the IB properties/materials 3
matrix.
