Identification should include aspects of
- transparency
- hardness
- density
- boiling/melting points
- conduction vs. resistance
- elasticity
- plasticity
- brittleness
- fatigue
of materials such as
- wood
- plastics
- metal
- concrete
- glass.
Process/Skill Questions:
- Why is understanding the properties of materials essential when working with those materials?
- What is fatigue in relation to material wear and tear?
- How do engineers rely on scientific knowledge to help understand materials?
