Biology Stage 6 - Year 12 - Module 6: Genetic Change Module 6: Genetic Change

Outcomes

A student:

  • BIO11/12-6

    solves scientific problems using primary and secondary data, critical thinking skills and scientific processes

  • BIO11/12-7

    communicates scientific understanding using suitable language and terminology for a specific audience or purpose

  • BIO12-13

    explains natural genetic change and the use of genetic technologies to induce genetic change

Content Focus

Students learn about natural and human-induced causes and effects of genetic change, including mutations, environmental pressure and uses of biotechnology. Students investigate how the processes of inheritance and evolution are applied.

The work of scientists in various fields of work, including agriculture, industry and medicine, can be explored within the context of biotechnology. The impact of biotechnology on biological diversity is also explored in this module.

Working Scientifically

In this module, students focus on analysing trends and patterns and solving problems using evidence from data and information. Students also focus on communicating ideas about genetic change for a specific purpose. Students should be provided with opportunities to engage with all Working Scientifically skills throughout the course.
