scientific knowledge, skills and data can be used by people to explain how they will meet a need or solve a problem

• investigating how understanding of life cycles of insect pests such as fruit flies led to effective control strategies
• investigating how engineers test the insulation properties of materials, and how this information is used to design food and beverage packaging, building insulation and clothing
• exploring how knowledge of the properties of plastic has influenced people to change how they purchase, use and dispose of plastic products
• recognising Aboriginal and/or Torres Strait Islander Peoples’ knowledges and understandings of evaporation and how the effect of evaporation can be reduced to conserve water, such as by digging flask-shaped wells designed to limit evaporation by creating a narrow entrance
• investigating human-constructed ways to store water such as dams, wells, artificial lakes, irrigation canals, pipes and water towers, and considering why people are encouraged to save and recycle water and to take actions that can be taken to reduce water consumption and waste
• examining how people use knowledge of friction to improve car and bicycle safety on slippery surfaces such as wet or icy roads
• investigating how knowledge of magnetic force is used to sort metals in recycling, mining and food processing
