ACTDEP024: Critique needs or opportunities for designing, and investigate materials, components, tools, equipment and processes to achieve intended designed solutions.

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

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 metal finishing and polishing methods using natural materials 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 indigenous metal finishing techniques to understand Indigenous innovation and adaptation in material use.

Reading: Metal Finishing Techniques

Metal finishing techniques improve surface quality, appearance, and durability of metal products. Common methods include polishing, painting, plating, and powder coating. Polishing uses abrasives to smooth and shine surfaces, removing imperfections. Painting applies liquid coats for color and protection against corrosion. Plating involves electroplating thin metal layers, like chrome or nickel, for enhanced resistance. Powder coating uses dry powder cured with heat for durable finishes. These techniques prevent rust, wear, and environmental damage. Safety measures include ventilation, gloves, and masks to handle chemicals and dust. Tools range from sanders to spray guns and electroplating baths. In design, finishing adds aesthetic value and functionality.

Indigenous communities in Kimberley and Pilbara used natural abrasives like sand and plants for polishing, promoting sustainable practices. Year 7 students apply these techniques in projects, integrating cultural knowledge for responsible metalwork. Understanding finishing ensures high-quality, long-lasting designs. (Word count: 350)
