Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as selecting strong woods like jarrah for spears and shields, to demonstrate respect for community values and sustainable design.

Cross-Curriculum Priority: Aboriginal and Torres Strait Islander Histories and Cultures - Students explore traditional wood use in crafts like spears and boomerangs to understand strength and sustainability in design.

Reading: Strength of Wood in Design

Wood's strength plays a crucial role in design applications allowing it to support loads and resist forces in various structures. Aboriginal and Torres Strait Islander peoples have utilized strong woods like jarrah for spears and shields due to their durability and ability to withstand impact. Hardwoods offer high compressive strength resisting crushing forces making them ideal for load-bearing elements like beams in construction. Softwoods like pine provide adequate strength for lighter applications such as furniture frames or shelving. Designers choose woods based on strength to create safe and sustainable products that meet personal and community needs. This ensures long-lasting use while promoting environmental responsibility.

Tensile strength allows wood to resist pulling forces making it versatile for designs like bridges or tools. Aboriginal knowledge selects flexible woods for boomerangs ensuring resilience and accuracy. Hardwoods excel in tensile strength supporting heavy loads without breaking. Softwoods have lower tensile strength but are easier to shape for custom projects. These properties guide ethical design choices integrating cultural values with modern needs. They meet community requirements for safe and reliable solutions.

Compressive strength enables wood to resist crushing forces supporting sturdy designs like furniture or buildings. Aboriginal crafts use dense woods for shields to withstand impact effectively. Hardwoods provide excellent compression resistance for load-bearing applications. Year 7 students explore safe wood use in design learning about strength and sustainability. This balances environmental care with practical strength requirements. Understanding wood strength helps create responsible designed solutions. (Word count: 312)
