Why study Biology?

Biology is the science of life; the study of all living things, from the smallest microscopic organisms to the largest lifeforms we know of. Biology explores the natural world we live in and how plants, animals and our own bodies work. Understanding why many living things are harmful and learning about them can help us overcome disease and infection.

Unit 1 – Cell Biology

This unit will examine cell biology and the applications of cell biology on our lives, and the implications on society. The key areas covered are:

National 4
· Cell division and its role in growth and repair
· DNA, genes and chromosomes
· Therapeutic use of cells
· Enzymes and their use in industry
· Micro-organisms and their use in industry
· Photosynthesis
· Respiration
· Controversial biological procedures

National 5
· Cell structure
· Transport across cell membranes
· Producing new cells
· DNA and protein production
· Proteins and enzymes
· Genetic engineering
· Photosynthesis
· Respiration

Unit 2 – Multicellular Organisms

This unit will examine multicellular organisms and their implications of cell on our lives, and on society. The key areas covered are:

National 4
· Sexual and asexual reproduction
· Propagating and growing plants
· Commercial use of plants
· Genetic information
· Growth and development of different organisms
· Maintaining stable body conditions

National 5
· Cells, tissues and organs
· Stem cells and meristems
· Control and communication
· Reproduction, variation and inheritance
· The need for transport
· Effects of lifestyle choices on animal transport and exchange systems

Unit 3 – Life on Earth

This unit will examine life on Earth and the applications of it on our lives, and the implications on society. The key areas covered are:

National 4
· Food webs
· Population growth
· Nitrogen cycle
· Fertilisers and their use
· Adaptations for survival
· Survival and learned behaviour

National 5
· Biodiversity and the distribution of life
· Energy in ecosystems
· Sampling techniques, and biotic and abiotic factors
· Adaptation, natural selection and evolution
· Human impact on the environment

Assessment

You will be assessed throughout the course in a variety of ways. Some of the assessments are for formative purposes to produce a profile report for you and your parents/guardians to show how you are getting on in each unit. These assessments will also help us decide which level National 4 or 5, you should aim for.

Other assessments are to provide evidence for SQA certification purposes and will be completed and marked following guidelines set by the SQA. These assessments will cover content and skills appropriate to National 4 or 5 levels.

National 4

Assessment Task 1 –
A scientific report of an experiment or practical investigation.
The report must include:
· A plan of the experiment including safety procedures
· Observations/measurements
· Results
· Conclusions
· Evaluation
YOU ONLY NEED TO COMPLETE ONE EXPERIMENT REPORT FOR THE COURSE.

Assessment Task 2 –
A short scientific report of a research investigation.
You will select and research an application of biology from one of the key areas you have studied. You must produce a report of 40 -70 words which identifies the key area and the impact of the application on the environment/society.
YOU ONLY NEED TO COMPLETE ONE RESEARCH REPORT FOR THE COURSE.

Assessment Task 3 –
A set of questions.
You will be given questions covering knowledge & understanding and problem solving under exam conditions.
YOU WILL GET A SET OF QUESTIONS FOR EACH OF THE THREE UNITS.

Added Value Assessment
You will investigate a topical issue in biology and its impact on society/the environment by:
· Choosing a relevant issue in biology
· Researching the issue
· Presenting appropriate information
· Explaining the impact, in terms of the biology involved
· Communicating your findings
You will be able to gather information over several weeks and you will be given no more than 2 hours under supervised conditions to write up your findings under open-book conditions. This will be marked by your class teacher.
YOU ONLY NEED TO COMPLETE ONE ADDED VALUE FOR THE COURSE.

Note: There is no final exam for National 4.

National 5

Assessment Task 1 –
A scientific report of an experiment or practical investigation.
The report must include:
· A plan of the experiment including safety procedures
· Observations/measurements
· Results
· Conclusions
· Evaluation
YOU ONLY NEED TO COMPLETE ONE REPORT FOR THE COURSE.

Assessment Task 2 –
A short scientific report of a research investigation.
You will select and research an application of biology from one of the key areas you have studied. You must produce a report of 50 -100 words which identifies the key area and the impact of the application on the environment/society.
YOU ONLY NEED TO COMPLETE ONE RESEARCH REPORT FOR THE COURSE.

Assessment Task 3 –
A set of questions.
You will be given questions covering knowledge & understanding and problem solving under exam conditions.
YOU WILL GET A SET OF QUESTIONS FOR EACH OF THE THREE UNITS.

Added Value Assessment
You will investigate a topical issue in biology and its impact on society/the environment by:
· Choosing a relevant issue in biology
· Researching the issue
· Presenting appropriate information
· Explaining the impact, in terms of the biology involved
· Communicating your findings
You will be able to gather information over several weeks and you will be given no more than 1 hour under supervised conditions to write up your findings under open-book conditions. This will be submitted to the SQA to be marked. It is worth a total of 20 marks.
YOU ONLY NEED TO COMPLETE ONE ADDED VALUE FOR THE COURSE.

You will sit a final exam which will test your knowledge & understanding from all the nits as well as problem solving skills. The exam will be sat under exam conditions in the hall. This will be submitted to the SQA to be marked. It is worth a total of 80 marks.
