AQA DT Specialist Technical Principles - Sources and origins

PowerPoint and accompanying worksheet with increase challenge questioning. This resource aligns with the AQA DT specification content;

Primary sources of materials and the main processes involved in converting into workable forms for at least one material area.
Paper and board (how cellulose fibres are derived from wood and grasses and converted into paper).
Timber based materials (seasoning, conversion and creation of manufactured timbers).
Metal based materials (extraction and refining).
Polymers (refining crude oil, fractional distillation and cracking).
Textile based materials (obtaining raw material from animal, chemical and vegetable sources, processing and spinning).

A tried and tested, very effective resource that can be used as a standalone lesson or as cover work
