Introduction 

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.

Inquiry question 2: How have developments in technology led to advances in scientific theories and laws that, in turn, drive the need for further developments in technology?

A. How has technology influenced the development of Scientific theories, laws and models?

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:

1.Computerised simulations and models of the Earth’s geological history

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

3.Technology to detect radioactivity and the development of atomic theory

4. The Hadron Collider and discovery of the Higgs boson

B. How has scientific theories, laws and models led to the development of new technologies?

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:

1.The laws of refraction and reflection on the development of microscopes and telescopes
