About the unit
Through this unit,
pupils should be able to:
- model a range
of locking and opening/closing mechanisms, and include these in their
own designs
- use a modelling
system to create strong and stable structures for testing security devices
- integrate the
structural and mechanical elements of a modelling system to create complex
working models
- design computer-controlled systems that control a range of output devices and monitor a range of input signals
- implement designed
computer-controlled systems so that they respond to real signals and
control real devices.

Product evaluation
Organise a range
of activities that give pupils an opportunity to:
- examine, describe
and evaluate the various ways in which different types of property are
kept secure (including electronic, physical and social)
- investigate a
range of approaches to allow authorised access and to warn of security
violations
- explore and evaluate
the working of a range of electronically controlled devices, including
those that incorporate embedded computer control
- examine some of
the values issues that are raised by introducting security systems.

Design and make
assignment
During the DMA, pupils
would be expected to:
- research the background
to the setting, survey existing security solutions and use the information
they collect to inform their own designing
- put together
a design specification
- discuss, as a
group, how they can use output devices and sensors in their design ideas
- make preliminary
models to explore and test their thinking
- experiment with
alternative designs and model mechanisms to establish correct working
before they decide on their final proposal
- propose appropriate
control systems and sub-systems
- prepare an ordered
sequence for managing the task
- evaluate their
product by comparing it with design criteria at chosen stages in its
development.
