In this unit pupils learn about control technology through modelling the working of a car park barrier. Pupils program a simple cause and effect model, eg pressing an input switch that produces an output, such as sounding an alarm, and develop their knowledge and understanding of control devices by solving a problem using procedures as building blocks. They refine instructions and learn how the order in which instructions are given will be critical to the success of the project. It is important that during this unit pupils use a structured approach to solving this type of problem.
The idea that a counter is used as a control mechanism is important, because it has many applications to everyday life. Pupils also develop their understanding of how criteria are used to make judgements about the success of their projects and areas of development.
This unit is expected to take approximately 5 hours.
