Do we challenge students enough? Model Solar vehicle project challenges potential engineers.

A major challenge to Australia and New Zealand is the perceived need to develop "knowledge economies" based on the expertise of university graduates,  especially engineers. However, many countries are finding less students are choosing to study engineering. At the same time, there is increasing concern about increased levels of greenhouse gases leading to global warming with species loss, rising sea levels and desertification being likely outcomes. Numerous competitions have been established aimed at attracting school students into science and engineering careers. Environmental groups have also sponsored educational activities to increase student awareness of alternative energy technologies. One activity which provides both a science and engineering challenge while also raising awareness of alternative energy and more efficient conversion of that energy for transport is the Model Solar Vehicle Challenge (MSVC). The Challenge, which provides a solar powered boat competition for younger students and a car race for the older ones, has involved thousands of Victorian school students since 1990 and students from all Australian states since 1993. Boats race in 2 or 3 lanes guided by an overhead wire in a 10 metre pool, and cars race 100 metres around a figure 8 track. Top boats average over 7 kph and cars reach speeds of 25 kph at the finish line. This paper will discuss the conduct of the Challenge, motivation of participants, the depth of learning which can be achieved and the effectiveness of the Challenge in encouraging students to continue with science subjects through school and to select engineering at university. It will also briefly discuss the lessons that can be learnt from the MSVC and applied to first year university courses.
