The main aim of this unit is for pupils to learn how to apply and combine their understanding of electrical and mechanical control and structures when designing and making. They can also develop and practise graphic communication techniques.
In this unit, pupils tackle a design and make assignment (DMA) on the theme 'Point-of-sale display', in which they produce an eye-catching display that communicates clearly and uses simple control of movement, light or sound.
Pupils gain the knowledge, skills and understanding they need to carry out the DMA successfully through product evaluation activities and focused practical tasks. They:
- model, design and construct simple electrical control circuits that include switches and outputs in parallel and series, protection of LEDs and reversing control of motors
- classify motion into four kinds and describe mechanisms that can be used to change one kind of motion into another
- use cams and linkages to create a particular kind of motion
- design and carry out fair tests to compare the strength of frame and sheet structures
- design and make structures that are strong, using their knowledge of structural strength
- consider different approaches to product marketing
There are also opportunities for pupils to:
- solder components and wires together effectively and safely when constructing simple electrical control circuits
- use a range of graphic techniques to create lettering and recognise their relative merits in different situations
- select appropriate lettering styles for a particular purpose
- use levers to change the amount and force of a movement in a planned way
- use CAD/CAM (computer-aided design and manufacture), where appropriate, to produce high-quality lettering and other graphics,
eg logos
