Year 7 Lesson: Investigating and Defining Wood

Curriculum Links

ACTDEP035: The nature of materials and their properties in design and technologies, such as timbers in woodwork.

ACTDEP036: Generate, develop, test and communicate design ideas, plans and processes for various audiences using appropriate technical terms and technologies including graphical representation techniques.

ACTDEP037: Select and justify choices of materials, components, tools, equipment and techniques to effectively and safely make designed solutions.

Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as traditional timber use in the Kimberley and Pilbara regions, to demonstrate respect for community values and environmental stewardship.

Cross-Curriculum Priority: Aboriginal and Torres Strait Islander Histories and Cultures - Students explore pre-contact and contemporary uses of Australian timbers to understand Indigenous innovation and adaptation in material use.

Reading: Investigating and Defining Wood

Investigating and defining wood involves analyzing its properties to determine suitability for design projects. Key properties include strength, durability, grain, and density. Strength is investigated through testing compression and tension. Durability is defined by resistance to decay and pests. In Western Australia, timbers from the Kimberley and Pilbara are investigated for these qualities. Kimberley bloodwood is defined as high strength for load-bearing structures. Boab wood is investigated for durability against weathering. Pilbara mulga is defined for excellent durability in harsh conditions, used for fencing. Gidgee is investigated for strength in tools.

Aboriginal practices investigate and define woods like bloodwood for spears and gidgee for boomerangs, considering grain and density. Jarrah is investigated for durability in flooring. Modern design defines wood properties for sustainable products. Investigating methods include bending tests to define strength. This ensures safe and effective design solutions. (Word count: 265)
