The rapid development of new technologies has enhanced industrial and agricultural processes, medical applications and communications. Students explore the dynamic relationship between science and technology where the continuing advancement of science is dependent on the development of new tools and materials. They also examine how advances in science inform the development of new technologies and so reflect the interdependence of science and technology.

Students consider experimental risks as they engage with the skills of Working Scientifically. They investigate the appropriateness of using a range of technologies in conducting practical investigations, including those that provide an accurate measurement.

In this module, students focus on developing hypotheses and questions and process appropriate qualitative and quantitative data. They demonstrate how science drives demand for the development of further technologies. Students should be provided with opportunities to engage with all Working Scientifically skills throughout the course.

  • Harvesting Knowledge-University of Sydney
  • IN TRADITIONAL ABORIGINAL CULTURE, the concept of healing an individual through the natural environment – using bush medicine – was ultimately entwined with the spiritual world and not just the physical. A healer was not just a ‘bush clinician’, but also an expert medium operating between the sick and the spiritual world.
  • Aṉangu Pitjantjatjara Yankunytjatjara (APY) lands, South Australia: In 2012, a group of Aboriginal traditional healers—ngangkaṟi—from the APY lands came together with a mission to strengthen traditional practices and medicines, and a vision for a complimentary, ‘two-way’ healthcare system.
  • Indigenous community television includes many stories and information from ATSI perspectives.
  • Historian Lynette Russell says science is starting to catch on to medicinal and environmental knowledge Indigenous Australians have held for generations but progress is slow.
  • The information and resources contained in this guide provide a platform for teachers and educators to consider how to effectively embed important ideas around reconciliation, and Aboriginal and Torres Strait Islander histories, cultures and contributions, within the specific
    subject/learning area of Science. Please note that this guide is neither prescriptive nor exhaustive, and that teaching staff are encouraged to consult with their local Aboriginal and Torres Strait Islander community in engaging with the material contained in the guide.
  • Biological Diversity and Indigenous Knowledge. This link is from the Parliament of Australia. The challenge is to protect the rights of Indigenous peoples to their knowledge, while also conserving biological diversity. The Convention on Biological Diversity is one international instrument that has the potential to achieve both these objectives. Its primary objective is the conservation and management of biological diversity. It also provides opportunities for the protection of Indigenous knowledge practices and innovations related to biodiversity and for the introduction of measures for equitable sharing of benefits with traditional knowledge holders.
