5.3 Materials
A material is a substance used for making
objects. Materials can be classified into 5 main
groups.
MATTER
fibres
metals
glass
ceramics
plastics

• shiny
• good conductors of heat and electricity
• can be bent and beaten into different shapes
  without breaking
• some metals corrode easily while others do not
