National 3 Environmental Science

 

National 3 Environmental Science is made up of the following units.

Living Environment (National 3)

The key areas of this unit are; sampling and identifying living things, from different habitats, to compare their diversity; factors influencing the distribution of living things; the process of photosynthesis and why plants are vital to sustaining life on Earth; the use of different types of chemicals in agriculture and their alternatives; and the potential impact of chemicals and their alternatives on the world’s food production.

Earth’s Resources (National 3)

The key areas of this unit are; renewable energy sources including benefits and potential problems; formation, characteristics and uses of minerals; formation, characteristics and uses of common rocks; formation, characteristics and uses of soils; and useful substances which can be extracted from natural resources.

Sustainability (National 3)

The key areas of this unit are; processes which may contribute to climate change; the possible impact of atmospheric change on the survival of living things; and the causes and possible consequences of an environmental issue, and ways to manage the impact.

Assessment

To achieve the National 3 Environmental Science Course, learners must pass all of the required Units. National 3 Courses are not graded.

National 4 Environmental Science

National 4 Environmental Science is made up of the following units.

Living Environment (National 4)

The key areas covered are: interdependence; adaptation for survival; the impact of population growth and natural hazards on biodiversity; and the nitrogen cycle and the environmental impact of fertilisers.

Earth’s Resources (National 4)

The key areas covered are: the responsible use and conservation of non-renewable and renewable resources; the formation and use of fossil fuels; the derivation and uses of materials derived from crude oil; the risks and benefits of different energy sources, including those produced from plants; the carbon cycle and processes involved in maintaining the balance of gases in the air, and the causes and implications of changes in the balance.

 Sustainability (National 4)

The key areas covered are: the sustainability of key natural resources and possible implications for human activity; the interaction between humans and the environment and the impact of human activity on an area; the role of agriculture in the production of food and raw material and its environmental impacts and sustainability; society’s energy needs and the impact of developments in transport infrastructure in a selected area; and development of sustainable systems.

Added Value Unit: Environmental Science Assignment (National 4)

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.

 Assessment

To achieve the National 4 Environmental Science Course, learners must pass all of the required Units, including the Added Value Unit. National 4 Courses are not graded.

National 5 Environmental Science

National 5 Environmental Science is made up of the following units.

 Living Environment (National 5)

This unit will be within the main themes of ecosystems, inter-relationships, and biodiversity. Practical activities could include fieldwork to sample and identify living things and measure non-living factors in an ecosystem. The Key areas covered are: Investigating ecosystems and biodiversity; Interdependence and Human influences on biodiversity.

Earth’s Resources (National 5)

The key areas covered are: an overview of Earth systems and their interactions; the geosphere; the hydrosphere; the biosphere and the atmosphere.

Sustainability (National 5)

The key areas covered are: an introduction to sustainability; food; water; energy and waste management.

 Assessment

To gain the award of the Course, the learner must pass all of the Units as well as the Course assessment. Course assessment will provide the basis for grading attainment in the Course award.
