  • Generate, develop, model and communicate their ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design

 

Make

Pupils should be taught to:

  • Select from and use a wider range of materials and components, including construction materials, textiles and ingredients, according to their functional properties and aesthetic qualities

 

Evaluate

  • Investigate and analyse a range of existing products
  • Evaluate their ideas and products against their own design criteria and consider the views of others to improve their work

  • Apply their understanding of how to strengthen, stiffen and reinforce more complex structures
  • Understand and use mechanical systems in their products [for example, gears, pulleys, cams, levers and linkages]
