1 Engineering (2010) Sample work program A September 2010

2 Engineering (2010) Sample work program A Compiled by the Queensland Studies Authority September 2010 A work program is the school s plan of how the course will be delivered and assessed, based on the school s interpretation of the syllabus. The school s work program must meet syllabus requirements, and indicate that there will be sufficient scope and depth of student learning to reflect the general objectives and meet the exit criteria and standards. This sample demonstrates one approach, and should be used as a guide only to help teachers plan and develop school work programs. 2 Engineering (2010) Sample work program A

3 Notes 1. Course Organisation A minimum of 55 hours of study per semester will be allocated to the course. Workshop, laboratory, CADCAM and robotics facilities are utilised throughout the course. Associated projects are structured around an engineering design process. From time to time the school may have composite Year 11 and Year 12 classes studying Engineering. Consequently, the work program has been presented as a two-year course, designated Year A and Year B, rather than as Year 11 and Year 12. The program will be taught so that the Year A and Year B components of the course will run consecutively, not concurrently. All students in any one year shall study the same subject material.

Outline of intended student learning Sample Unit of Work Efficient vehicles Year B Semester 4 Term 4 Contexts: Sustainability, Transportation, Energy The, and Mechanics subject matter will be contextualised to provide a real-world focus in relation to energy-efficient vehicles and associated issues of sustainability, transportation and energy. Students will undertake a spring-powered vehicle project that is structured around an engineering design process. The study topics outlined below are studied and integrated into the practical project. Workshop/laboratory facilities are utilised with designing, making and testing of vehicles. Subject Matter, (2 weeks) Study Topics Evolution and influence of technology on Sustainable engineering Subject Matter Influence of advances in engineering on technological change and the effect on Social, economic, environmental and cultural implications, including Indigenous cultures Future perspectives Social: sustainability principles, sustainable living, recycling Environmental: clean technology, nuclear energy, biofuel, geothermal power, hydropower, solar power, tidal power, wave power, wind power, carbon sinks Engineering Mechanics (6 weeks) Study Topics Dynamics Machines Subject Matter Displacement, velocity and acceleration.

6 Control Systems (1 week) Study Topics Fundamentals of control systems Subject Matter Control elements input, process, output; Applying control systems Simulation of integrated systems using modelling techniques Flow charts, event-timing diagrams Practical application of control systems using input/output devices connected to a control device Learning Experiences Students will: apply the engineering design process learn engineering knowledge, principles and techniques through teacher instruction undertake and solve engineering problems by applying learned procedures and techniques make use of testing techniques undertake laboratory testing communicate solutions to others using a variety of techniques, including modelling, simulation and extended writing apply basic scientific skills interpret tables and graphs related to mechanical testing and engineering mechanics sketch graphical solutions use computer technology and automation investigate current issues in engineering work individually to analyse and draw conclusions relevant to engineering problems critically examine the role of technology and its impact on, the environment and local Indigenous communities. Practical Project Energy technology is the application of a range of energy sources and their conversion into power in a controlled manner. It is concerned with the efficient, safe, environmentally friendly and economical extraction, conversion, transportation, storage and use of energy. Sustainability is the application of engineering principles in a manner which propagates, promotes and sustains a liveable planet for future generations. The development of renewable energy sources free of climate changing gases and by-products is the core concern for this area of engineering technology. Transportation technology is the application of resources to move materials, goods and people safely, more efficiently and more cost-effectively. It examines the impact of transportation on the environment and aims to reduce pollution with more fuel-efficient cars, computer monitoring of emissions, and public transportation systems. 6 Engineering (2010) Sample work program A

7 The engineering design process will be applied by students to design and make a model vehicle powered by a spring that incorporates a simple control system. The model vehicle will be required to move a load. Students will analyse and relate their models to advances in engineering including modern transport technologies and the sustainable use of energy. Students analyse the 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, and aesthetic qualities. Students will produce a folio of work. The design problem is open-ended in nature, which means there may be more than one correct solution. In this project students are required to: identify the elements of the problem students should state the problem in their own words, describing the aspects that are known and what is unknown recall, select and apply relevant engineering knowledge students should research and investigate current best practice in the field, noting relevant information and the design implications interpret and analyse engineering data students should investigate the design specifications, identify constraints and information gathered. Students should also identify relevant mathematical concepts and engineering principles propose possible solutions students should propose possible solutions based on 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 relevant to the engineering problem select and evaluate a solution students should identify the design that appears to solve the problem most effectively. They describe and justify why they chose the solution. This should include some reference to the specifications and constraints identified above as well as relevant mathematical concepts and engineering principles prototype and test the solution students should produce a full-size model based on their drawings. They should identify appropriate modelling environments, materials and tools. They should test their model and gather relevant mathematical and scientific data to determine its effectiveness draw conclusions and make recommendations students should interpret and analyse test data and analyse and evaluate their prototype in relation to the identified elements of the initial engineering problem. Students should apply relevant engineering knowledge to identify any problems and suggest proposed modifications. Communication of engineering knowledge is integral to the entire engineering design process.
