Students are involved in a decisionmaking process that leads to the development of a bridge structure to meet a need. Among the fundamental elements of this PLEASE NOTE: This is a sample provided by a school. It is not an official publication of the QSA. Queensland Studies Authority Revised: October

10 process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and modelling, evaluation and communication. Students are asked to analyse a clearly defined structural problem and select and apply engineering knowledge, mathematical concepts and techniques to propose a workable solution to the problem. Their solution should take into account factors such as sustainability and environmental impact, cost effectiveness, safety considerations, aesthetic qualities, and, in terms of the technology, appropriateness for the societal needs. Students then produce a teacher directed folio of work. The project involves mathematical concepts and techniques, investigative and analytical processes, in which students test and model bridge solutions. The design problem is open ended in nature, which means there may be more than one correct solution. Solving a design problem through an engineering design process is iterative, i.e. the desired result is reached by means of a repeated cycle of operations. It is a non-linear process in which problems and processes are identified, revisited, challenged, reconsidered, reexamined and solved at each and any stage of development. In this unit students are required to: analyse the problem students should state the problem in their own words, for example, a design solution is needed that will perform a particular task investigate related engineering knowledge students should research and investigate current best practice in the field, noting relevant information and the design implications analyse elements and specifications students should state the design specifications and identify constraints. Students should also identify related mathematical and scientific concepts propose possible solutions students should propose possible solutions based on the research. Annotated sketches should identify the key features and explain the preliminary concepts analyse solutions students should analyse proposed solutions and identify the critical elements related to the engineering problem select and justify a solution students should identify the design that appears to solve the problem most effectively. They should write a statement that describes why they chose the solution. This should include some reference to the specifications and constraints identified above as well as related mathematical and scientific concepts prototype and test the solution students should produce a full-size or scale model based on their drawings. They should identify appropriate modelling environments, materials and tools. They should test their model and gather related mathematical and scientific data to determine its effectiveness evaluate the solution students should examine and evaluate their prototype based on the initial engineering problem. Students should identify any problems and suggest proposed modifications.
