About the unit
Through this unit,
pupils should be able to:
Food
- apply their understanding
of the nutritional and working characteristics of food components when
selecting materials/ingredients and matching them to making processes
- learn how to use
heat treatment and other processes to change the working properties
of materials/ingredients
- learn about the
diversity of one food product and the influence of culture and lifestyle
- consider minimising
environmental damage and use materials/ingredients sympathetically
- use hedonic ranking
on a five-point scale, difference tests and appropriate vocabulary
- learn about the
uses of modern materials/ingredients
- investigate the
basis of concerns about biodiversity, genetically modified crops, and
the use of growth hormones and antibiotics in the production of food.
Resistant materials
- understand that
the properties of materials influence what they select for a design
- select materials
and match them to appropriate making processes
- learn how to use
heat treatment and other processes to change the working properties
of materials
- learn about the
diversity of one product and the influence of culture and lifestyle
- consider minimising
environmental damage, use materials sympathetically, and find out about
the importance of reuse and recycling issues
- conduct fair test
procedures using qualitative and quantitative measures
- learn about the
uses of modern materials
- consider different
structural designs to withstand greater loads
- redesign products
to distribute the forces of tension, compression and shear more evenly
throughout a product.
Textiles
- understand that
the properties of materials influence what they select for a design
- select materials
and match them to appropriate making processes
- learn how to use
heat treatment and finishing processes to change the working properties
of materials
- learn about the
diversity of one product and the influence of culture and lifestyle
- understand how
textile materials can be combined to develop specific products and effects
- consider minimising
environmental damage, use materials sympathetically, and find out about
the importance of reuse and recycling issues
- understand how
to test fabric against a specification before going into production,
and how to follow fair test procedures using qualitative and quantitative
measures
- learn about the
uses of modern materials.

Product evaluation
Organise a range
of activities that give pupils an opportunity to:
- learn about the
diversity of a product
- consider possible
recycling and disposal of the materials used
- explore the use
of modern materials.

Design and make
assignment
During the DMA, pupils
would be expected to:
- 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, considering their fitness for purpose and environmental impact
- specify and justify
the exact types and grades of materials, and give details of processing
methods in the specification
- prioritise and
reconcile decisions on materials, time and production
- use materials
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.
