Content descriptor investigate how scientific knowledge is used by individuals and communities to identify problems, consider responses and make decisions

Elaborations

• • Elaboration considering how decisions are made to farm particular crops or animals depending on local habitats, such as considering their ability to withstand drought or cold weather
• • Elaboration examining how communities use knowledge of erosion processes to design landscape features that reduce erosion in fragile environments
• • Elaboration examining how knowledge of erosion is used by park rangers to design rules such as keeping to the path and not climbing sandstone, and built features such as channel drains on paths, railings and barriers to protect the park environment and First Nations Australians’ heritage sites
• • Elaboration researching the impacts of light pollution and exploring how communities have used scientific knowledge to reduce light pollution, such as through the use of covered bulbs facing downwards in streetlights, automated systems to turn off streetlights and motion sensors on outdoor lights at home and in public places
• • Elaboration investigating how and why people used properties of light to design signal lamps to communicate via Morse code and where they continue to be used
