Recommended Entry Requirements

 

To gain entry into the National 3/4 Science you should have a recommendation from your current science teacher and at least one of the following:

-          successfully completed one or more of the S3 Science unit courses to a high standard

-          completed one of the S3 discrete Science subjects (Chemistry, Physics or Biology)

 

Class Organisation

 

Learners who opt for the National 3 or National 4 Science will be taught in the same class with both National 3 and National 4 content and skills being covered throughout the course. You will be certified in just one level (either National 3 or 4) 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.

 

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.

Unit 1 – Fragile Earth

This unit will look at water, food, energy and materials. The key areas covered are listed in the table below. Note that only two areas will be covered. Which areas are covered may vary from year to year.

 

National 3

National 4

·        Water – conflicts, benefits and solutions to issues in uses of water, including sources and origins of drinking water, and the extraction of water.

·        Food – conflicts and issues associated with food production, including plant and livestock farming, impact of technology and impact of farming on the environment.

·        Energy – conflicts and issues associated with production and use of energy, including generation of power from a range of sources (fossil fuels, plants, renewable), risks and benefits of energy sources, sustainable use of energy.

·        Metals – conflicts and issues with the extraction of metals, including properties of metals, methods of extraction, abundance and sources, impact of metal extraction on the environment and recycling of metals.

·        Water – conflicts, benefits and solutions to issues in uses of water, including sources and origins of drinking water, and the extraction of water.

·        Food – conflicts and issues associated with food production, including plant and livestock farming, impact of technology and impact of farming on the environment.

·        Energy – conflicts and issues associated with production and use of energy, including generation of power from a range of sources (fossil fuels, plants, renewable), risks and benefits of energy sources, sustainable use of energy.

·        Metals – conflicts and issues with the extraction of metals, including properties of metals, methods of extraction, abundance and sources, impact of metal extraction on the environment and recycling of metals.

 

Unit 2 – Human Health

This unit will examine human health, threats to health and health claims.

The key areas covered are:

 

National 3

National 4

·        What is health? – aspects of social, physical and mental health.

·        Threats to health – health issues

·        Health claims – review of health claims.

 

·        What is health? – How to keep healthy and understanding the impact of nutrition on health.

·        Threats to health – preventative measure including the understanding of the immune system and the use of vaccines.

·        Health claims – review articles and information in the media.

 

Unit 3 – Applications of Science

This unit will examine telecommunications, materials, risks and health and safety. The key areas covered are:

 

National 3

National 4

·        Telecommunications - principles and applications of tele-communications, electromagnetic waves and sound waves.

·        Materials – material source, production, properties, uses, benefits and issues.

·        Risks and health and safety – risks and minimising risks in the home, work and transport.

 

 

·        Telecommunications – principles and applications of tele-communications, uses and properties of electromagnetic waves.

·        Materials – including properties of substances, properties and uses of novel materials, and impacts, risks and benefits of their use.

·        Risks and health and safety – measures associated with science at work including chemical, radiation and electrical risks and safety.

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 3 or 4, 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 3 or 4 levels.

 

 

 

National 3

National 4

Assessment Task 1 -

There is no Added Value assessment for National 3.

 Added Value Assessment

You will investigate a topical issue in science and its impact on society/the environment by:

  • Choosing a relevant issue in science
  • Researching the issue
  • Presenting appropriate information
  • Explaining the impact, in terms of the science 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.

YOU ONLY NEED TO COMPLETE ONE ADDED VALUE FOR THE COURSE.
