(SCQF Level 6)
The Higher Biology course provides opportunities for learners to acquire and apply knowledge to evaluate biological issues, assess risk, make informed decisions and develop an ethical view of complex issues. Throughout the course, learners are able to develop their communication, collaborative working and leadership skills, and are able to apply critical thinking in new and unfamiliar contexts to solve problems.
Higher biologists use an experimental and investigative approach to develop knowledge and understanding of concepts in biology. Due to the interdisciplinary nature of the sciences, learners may benefit from studying biology along with other science subjects and mathematics, as this may enhance their skills, knowledge and understanding.
It is advised that learners have a high level of confidence in their learning and attainment at National 5 level biology, alongside English and mathematics in order to have the best chance of success at Higher level.
This course allows learners to develop deeper understanding of the underlying themes of biology. The scale of topics ranges from molecular through to whole organism and beyond. Developing an understanding of DNA and how the structure of the genome leads to the basis of evolution and biodiversity. Genomics is studied as one of the major scientific advances in recent times. Metabolic pathways and their control are considered along with the conditions in which organisms survive and their means of coping with these. The interdependence and complex interactions between organisms is explored and sustainable food production, with the fundamental process of photosynthesis at its core, is investigated.
The development of skills enables candidates to adapt their learning to new situations, solve problems, make decisions based on evidence, and evaluate the impact of scientific developments on their health and wellbeing, society and the environment. By setting the acquisition of knowledge and skills in the context of Higher Biology, a stimulating, relevant and enjoyable curriculum prepares candidates for further education, training or employment, in areas associated with life sciences.
The course content includes the following areas of biology, across three units of work:
DNA and the genome. The key areas covered are: structure of DNA; replication of DNA; gene expression; cellular differentiation; the structure of the genome; mutations; evolution; genomic sequencing.
Metabolism and survival. The key areas covered are: metabolic pathways; cellular respiration; metabolic rate; metabolism in conformers and regulators; metabolism and adverse conditions; environmental control of metabolism; genetic control of metabolism.
Sustainability and interdependence. The key areas covered are: food supply, plant growth and productivity; plant and animal breeding; crop protection; animal welfare; symbiosis; social behaviour; components of biodiversity; threats to biodiversity.
The Higher Biology course is assessed by two written papers, set and marked by the SQA.
