About the unit
Through this unit,
pupils should be able to:
Food
- apply their understanding
of the physical and chemical properties of foods
- consider the aesthetics
of food, and how this affects what consumers choose
- consider nutritional
aspects and values, sources and functions
- standardise the
results of sensory testing and use their findings.
Resistant materials
- apply their understanding
of the properties of materials
- consider more
complex finishing processes, including their potential environmental
impact and health hazards
- use thermoforming
processes
- identify methods
of using the structural properties of metals when reinforcing and strengthening
frames
Textiles
- find out about
the processing of raw materials and potential end uses
- recognise the
connections between the properties of fibres, their performance and
how they are used
- learn how the
properties and working characteristics of textile materials relate to
their composition, construction and finishing, and how synthetic fibres
can be made to emulate natural fibres
- identify methods
for reinforcing and strengthening textiles.

Product evaluation
Organise a range
of activities that give pupils an opportunity to:
- identify the properties
of different materials and components and consider why they have been
used
- learn about the
structural properties of materials
- identify possible
design weaknesses in the choice or processing of the materials used
- name and describe
the methods and processes used to make and finish the product
- specify design
criteria and set up tests to evaluate products objectively
- learn words to
describe the form and function of products.

Design and make
assignment
During the DMA, pupils
would be expected to:
- take into account
appearance, function, safety and reliability
- make preliminary
models to explore and test their design thinking
- make their product
within constraints
- use their knowledge
of how databases are organised, and how to read them to select relevant
technical information about materials and processes
- consider a range
of materials and methods
- choose materials
and methods, and give details of these in a manufacturing specification
- write a report
(300 words) justifying and reviewing their choice of materials and
methods of making. The report should have a clear focus and include
linked paragraphs and topic sentences.
