Technologies

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 accurate measurement.

Scientific Investigation and Technology

HOW DOES TECHNOLOGY ENHANCE AND/OR LIMIT SCIENTIFIC INVESTIGATION?

 

design a practical investigation that uses available technologies to measure both the independent and dependent variables that produce quantitative data to measure the effect of changes of, including but not limited to:

– temperature on reaction rate
– temperature on volume of gas
– speed on distance travelled
– pressure on volume of gas

 

conduct the practical investigation to obtain relevant data and evaluate the limitations of the technologies used

 

investigate the range of measuring devices used in the practical investigation and assess the likelihood of random and systematic errors and the devices' degree of accuracy

 

using specific examples, compare the accuracy of analogue and digital technologies in making observations

 

assess the safety of technologies selected for the practical investigation by using chemical safety data and Work Health and Safety guidelines as appropriate

 

A Continuous Cycle

How have developments in technology led to advances in scientific theories and laws that, in turn, drive the need for further developments in technology?

 

using examples, assess the impact that developments in technologies have had on the accumulation of evidence for scientific theories, laws and models, including but not limited to:

– computerised simulations and models of the Earth’s geological history

– X-ray diffraction and the discovery of the structure of deoxyribonucleic acid (DNA)

– technology to detect radioactivity and the development of atomic theory

– the Hadron collider and discovery of the Higgs boson

 

using examples, assess the impact that developments in scientific theories, laws and models have had on the development of new technologies, including but not limited to:

– the laws of refraction and reflection on the development of microscopes and telescopes

– radioactivity and radioactive decay on the development of radiotherapy and nuclear bombs

– the discovery of the structure of DNA and the development of biotechnologies to genetically modify organisms

– Newton’s laws and the technology required to build buildings capable of withstanding earthquakes

 

investigate scientists’ increasing awareness of the value of Aboriginal and Torres Strait Islander Peoples’ knowledge and understanding of the medicinal and material uses of plants and, in partnership with communities, investigate the potential for ethical development of new drug treatments and synthetic chemicals through the bioharvesting of plants from Country and Place
