Design project: All systems go
Summary of task
Students investigated two closed force systems (pneumatics and hydraulics) to understand that the technology of pneumatics relates to air pressure and the technology of hydraulics relates to water pressure. They were given a design brief to design a machine (incorporating pneumatics and/or hydraulics) to extract a rare dinosaur egg from a remote location and move it to a safe storage container. Students developed design ideas and communicated these using annotated drawings. They selected suitable materials to make a scale model of their design and gave an oral and visual presentation to the class describing how their machine worked (designed solution), which system they used and the reasons why decisions were made, problems faced and how they were resolved.
The focus of this task was to design and produce a service for the technologies context engineering principles and systems.
Achievement standard
By the end of Year 4, students describe how social, technical and sustainability factors influence the design of solutions to meet present and future needs. They describe features of technologies that influence design decisions and how a range of digital systems can be used.
Students outline and define needs, opportunities or problems. They collect, manipulate and interpret data from a range of sources to support decisions. Students generate and record design ideas for an audience using technical terms and graphical and non-graphical representation techniques including algorithms. They plan a sequence of steps (algorithms) to create solutions, including visual programs. Students plan and safely produce designed solutions for each of the prescribed technologies contexts. They use identified criteria for success, including sustainability considerations, to judge the suitability of their ideas, solutions and processes. Students use agreed protocols when collaborating, and creating and communicating ideas, information and solutions face-to-face and online.
