Evaluate product concepts related to ethical design, synthesise and apply feedback to justify a final proof of concept, and plan to make the product safely.
Detailed example
Demonstration of property testing
Demonstrate an appropriate workshop test for a property of a material, such as an abrasion test for hardness.
Ask students to work in pairs to carry out appropriate testing of a range of materials and take photos of the testing process. Students should write annotations to document the suitability of the material for a particular product. Note that these tests are part of the teaching and learning program and cannot be used for assessment purposes, including for the School-assessed Task (SAT).
Demonstrate an appropriate workshop test, such as impact resistance for a coffee tabletop. Select an item relevant to the product’s use and drop it from an appropriate height onto a variety of material samples.
Measure, where appropriate, and collect visual feedback to rank the materials from most to least impact resistant. For example, for a coffee table, an old remote control or metal drink bottle could be dropped from a height of 200mm onto a range of woods, such as pine, reclaimed timber or plywood.
Students should then carry out a test relevant to their product’s use. For example, students could undertake hardness testing by moving a coffee mug across a set distance on a material sample for a given number of times to see which material is the most scratch-resistant. The test could be repeated with an applied finish.
Students could test piling on a variety of textile samples suitable for a running top. The same textile samples could be rubbed together to determine any breaking and bobbling on the fabric surface. A range of fibre types can be tested and ranked.
Results can be photographed and inserted into the design folio along with observations and judgements relating to the design.
