Lesson Details
Key learning points
- Plants and animals are a natural source of materials, such as paper, board, timber and natural textiles.
- The earth is a source of materials such as those derived from fossil fuels or mined.
- Natural resources can be processed to create materials such as manufactured board, polymers and synthetic fibres.
Common misconception
Textiles are not made from fossil fuels.
Synthetic fibres are usually made from fossil fuels such a polyester and ripstop nylon.
