Students then negotiate and sign up for the jobs on offer with extra workers being assigned the roles of runners,supervisors or quality controllers. The use of prepared jigs and fixtures is explained and their vital role,in ensuring that repetitive work is done quickly and accurately,is heavily stressed. Finally,the jobs are demonstrated, the optimum lay-out of the room is agreed upon and the class is now primed to go into buggy production. Experience has shown that a class of 20 students can make 20 finished and fully operational buggies in under one hour. This compares with about a four-week timescale using individual production for the same task. A graphical element can be added at this point if‘bodywork’ in the form of card nets are made, decorated and fitted to the chassis with double-sided tape. This allows for extension work into areas such as airflow,resistance and drag. The practical aspect of the project concludes with the testing of the vehicles and,again,there are opportunities for extension work into stored energy,wheel-spin,friction,tyres and lubrication. It is also possible to achieve an efficiency rating for the buggy,by dividing the distance travelled by the number of turns of the rubber band. This can be calculated manually or by using a spreadsheet if an element of IT is included.
