National 4/5 chemistry
Pupils can achieve an N4 qualification by passing unit assessments and successfully completing the Added Value Unit.
The Course develops skills in a chemistry context. Learners will gain an understanding of chemistry, and develop this through a variety of approaches, including practical activities.
The Course has four mandatory Units including the Added Value Unit. The first three Units listed below are designed to provide progression to the corresponding Units at National 5.
1. Chemical Changes and Structure
In this Unit, learners will develop scientific skills and knowledge of the chemical reactions in our world. Through practical experience learners will investigate rates of reaction, energy changes of chemical reaction, and the reactions of acids and bases and their impact on the environment. Focusing on these reactions, learners will work towards the concept of chemical equations. Learners will research atomic structure and bonding related to properties of materials.
2. Nature’s Chemistry
In this Unit, learners will research the Earth’s rich supply of natural resources which are used by each and every one of us. Learners will investigate how fossil fuels are extracted and processed for use. They will investigate: the chemistry of using fuels, their effect on the environment and the impact that renewable energy sources can have on this; plants as a source of fuels, carbohydrates and consumer products; and how chemists use plants in the development of products associated with everyday life.
3. Chemistry in Society
In this Unit, learners will focus on the chemical reactions, properties and applications of metal and alloys. The chemistry of metals in chemical cells is explored. Through research, learners will compare and contrast the properties and applications of plastics and new materials. Learners will investigate the use of fertilisers, the formation of elements, and the presence of background radiation, and will research the use of chemical analysis for monitoring the environment.
Added Value Unit: Chemistry Assignment
In this Unit, learners will draw on and extend the skills they have learned from across the other Units, and demonstrate the breadth of knowledge and skills acquired, in unfamiliar contexts and/or integrated ways.
Conditions of award
To achieve the National 4 Chemistry Course, learners must pass all of the required Units, including the Added Value Unit.
To achieve a pass at N5 pupils are required to complete a assignment which contributes 20% towards their overall mark. Pupils are also required to sit a written exam, this contributes 80% towards their overall mark.
Learners gain an understanding of chemistry and develop this through a variety of approaches, including practical activities, investigations and problem solving. They research topics, apply scientific skills and communicate information related to their findings, which develops skills of scientific literacy.
The course content includes the following areas of chemistry:
1. Chemical changes and structure
