Recommended Entry Requirements

To gain entry into the National 4/5 Biology you should have a recommendation from your current science teacher and at least one of the following:

-          successfully completed the S3 Biology course

-          successfully completed the S3 Chemistry or Physics course to a high standard

-          successfully completed the Science course at National 4 level.


 

Class Organisation

Learners who opt for the National 4 or National 5 Biology will be taught in the same class with both National 4 and National 5 content and skills being covered throughout the course. You will be certified in just one level (either National 4 or 5) on successful completion of the appropriate SQA assessments. Which level you are finally assessed in will depend on your performance in assessments and class work throughout the year. The decision as to what level you should aim for will be made following the prelim exam.

 
 

Course Content

Each level consists of three units as summarised in the tables below. If you want more detailed information on the content covered go to the SQA website.

Revision

You should ensure that you spend time preparing thoroughly for all assessments at National 5 level. Below are some useful links to help you with your revision.

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

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 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.

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.
