Subject: Life Science

Subject Description:

Life Science is the branch out of Natural Sciences which deals with biological and living organisms. Life Science is an interesting subject as it includes the study of living organisms and life processes. Life Science lays the foundations for important disciplines including Zoology, Ecology, Bio Informatics, Biotechnology, Biomedical Research, Molecular Biology, Genetics, Haematology, Oncology, and Aerobiology.

Value of Life Science as subject:

Life Science students are required to develop both their theoretical and practical expertise during each year. Students need to change their studying perspective from studying to passing a test to obtain a more profound knowledge and understanding of various aspects to be applied to daily life.

The content learned in class is not limited to knowledge from books but must also be obtained through practical experiences outside the classroom. This attitude to learning will aid students in their future endeavours.

Critical thinking and analysis are essential as it enables students to understand the source of the evidence and the relationship between facts. Thinking allows students to identify bias and manipulation and develop their own informed opinions. These skills include problem-solving, following through on goals, and making informed decisions.

Students need to remember that science-related knowledge and scientific literacy provides essential tools for surviving the modern-day 'news jungle' and aid in responsible citizenship.

They also teach us to understand our actions, review them critically, and take care of our rights.

Studying life science is crucial as it helps students better understand the world's natural processes and how life evolves, survives and changes. It gives knowledge about the interaction of cells with organs and organisms, environment and ecosystem.

It also teaches how various organs and system works in the human body and how everything is connected in our body. It is an important subject from a medical perspective, including identifying disease and its cure.

Skills/Content Carried over from Grade 10-12:

Skill

Content

Writing and Presenting

Controlled writing tasks (essays and case studies)

Investigating and Reporting

Understanding how science works based on fundamental knowledge built on scientific evidence and verified findings

Conducting practical experiments

Observing, investigating, making measurements, and understanding the importance of scaling, collecting, and presenting data in the form of drawings, written descriptions, tables, and graphs. Understanding procedures and how to safely use apparatus in laboratories and classrooms

Interpretations and analysis of data

Understanding the limitations of scientific evidence, identifying patterns and relationships in data, understanding the importance of biological principles, the relationship between structure and function, applying principles to biological drawings translating 3 dimensional objects or specimens into 2 dimensional drawings and photographs and interpreting 2 dimensional drawings and photographs, transverse and longitudinal sections, calculating and using equipment and other resources

Grade 9 Requirements:

Students need to make sure that their Grade 8-9 foundation is solid when choosing this subject. Life Science at FET level consists of more content that needs to be covered requires students to constantly study and revise. Students are also required to apply this content to scenarios, rather than simply memorise it.

To achieve their potential in FET Life Science, students must make sure of the following:

Requirements

Content

Minimum Marks

Aim to achieve at least a 60% mark for Life Science at the end of Grade 9

Exam preparation

Study and revise content on a daily or weekly basis and keep notes and summaries up to date

Work ethics

Be ready to tackle a large amount of content each term

Time management skills

Have good time-management skills to keep on track with all tasks

Ask for help or assistance!

Be willing to attend extra lessons and ask questions when a concept is unclear
