Design and technology at key stage 3    (Year 9)

Unit 09ai: Selecting materials Focus: food
Section 1: Design and make assignment (DMA)

QCA

Objectives

Children should learn:
  • to design and make a product in which the optimum use of materials/ingredients reconciles a number of criteria, including the working characteristics, production processes, environmental and social issues, costs and aesthetics, by applying the knowledge, skills and understanding they developed during the product evaluation activities and focused practical tasks

Activities

Outcomes

Children:

Set the pupils a DMA in which they:

  • select materials/ingredients according to their characteristics and match them to appropriate making processes
  • evaluate the materials/ingredients chosen by using fair test procedures with qualitative and quantitative measures
  • explore the uses of modern materials/ingredients, and use them sympathetically

The DMA should also give the pupils an opportunity to discuss how we are all responsible for the wellbeing of others.

Example

This example DMA has been written so it can be copied and given directly to pupils. Further details and contexts can be added, as appropriate.

Specialist diets

People demand choice, whether they are eating a meal on an aircraft, in a restaurant or in a motorway service station, and meals and dishes have to be made to suit a range of different dietary needs. Many food outlets buy ready-prepared meals that can be kept frozen or chilled before being served to customers.

A company wants to buy a new meal to offer to customers with special dietary needs. Design a prototype of a suitable dish and present it to the company.

  • draw up a design specification and criteria that reflect users' needs
  • combine ideas from a variety of sources
  • refine a single idea from a range of ideas and draw up a manufacturing specification
  • match and select materials/ingredients, considering their fitness for purpose and environmental impact
  • specify and justify the exact types and grades of materials/ingredients, and give details of processing methods in the specification
  • prioritise and reconcile decisions on materials/ingredients, time and production
  • use materials/ingredients sympathetically
  • evaluate their product against the original design criteria and assess how well the users' needs have been met
  • write an account of the evaluation

Points to note

Language for learning when writing evaluations
  • Remind pupils that a written account of an evaluation could include:
    • an introductory paragraph that explains the assignment and the design issues
    • a paragraph for each design criterion
    • evidence of evaluation
    • a summary of success
    • a concluding paragraph that includes an overall evaluation, suggestions for future improvement, and a comment on what they have learnt during the DMA
