Year 9 Design Technology students recently held a ‘Race Day’. This event concluded a six-month design journey. Students began in February by learning about basic aerodynamics and how this applied to car design. Their task was to create a concept shape which they believed would get their racer across the line the fastest. Term 2 found the students learning to use Autodesk Inventor in order to produce the 3D model of their proposed racer. Once they had created their car it was placed into a virtual wind tunnel. Students then had the opportunity to tweak their design to improve its performance. Final solutions were then 3D printed and assembled ready for racing.
Race Day was a series of ‘knock-out’ races for the 36 cars. First round was a best out of three series for each pair of racers. The successful cars then proceeded onto the instant knock-out stages. After many races the grand final was between George White and James Walters, with James becoming the 2016 champion.
While racing was the highlight for the students, it was the conversations happening during the racing that demonstrated the skills they had acquired. All of the students were analysing the results for each race and putting forth their theory about how the aerodynamics work in action to help or hinder the cars.
