• Access to food and water:
• consequences of lack of access to food and proper nutrition
• ways of accessing food and water in different contexts, past and present
• wise use and management of these resources
Beliefs linked to natural features of local area.
Indigenous environmental practices.
Place names, names of rivers, mountains and other land marks.

Life and Living

Life processes and healthy living:
Summery: Green plants make the energy from the sun available to other living organisms.
• Green plants produce their own food and grow by using water and substances from the air and soil. Energy from light is needed to change these substances into food and plant material. Green plants are the only organisms that can produce food in their own bodies.

Interactions in Environments:
Summery: An ecosystem is where animals and plants and other natural elements co-exist in an inter-dependent fashion.
• Animals cannot make their own food, and so some animals eat plants for food while some animals eat other animals. All animals depend ultimately on green plants for their food.
• Ecosystems are self-contained areas where a wide variety of plant and animal species live and reproduce. They depend on one another and on the non-living environment. The life and reproduction of all organisms in an ecosystem depend on continuing growth and reproduction of plants.

Bio-diversity, Change and Continuity:
Summery: Plants reproduce through seed dispersal, bulbs and other methods.
• New plants can grow from certain parts of a parent plant. This is called vegetative reproduction and does not need seeds. The new plants have all the characteristics of the parent plant. (focus on our role in the agricultural sector and in the conservation of plant heritage)

The Planet Earth and Beyond

Atmosphere and weather
Summery: Most of earth consists of water, but not all of it is readily available to our disposal
• Water changes its form as it moves in a cycle between the hydrosphere, atmosphere and lithosphere in what is known as the water ‘cycle’.
• Most of planet earth is covered by water in the oceans. A small portion of the planet is covered by land that is separated into continents. At the poles there are ice caps. Only a small amount of water is available to living things on land to use and only a small portion of land is easily habitable by humans.

The Changing Earth
Summery: Proper management of the catcment areas is crucial to the quality of our water.
• Earth materials are solid rocks and soils, water and gasses of the atmosphere.
• The quality of water resources is determined by the quality of catchment area. Proper care and the management of catchment areas and water resources are essential, and factors affecting the quality of water resources and catchment areas may be investigated. (Links with Life and Living)

The Economic Cycle:
Summery: Personal responsibility regarding resources
Explain the effects on the community of both responsible and irresponsible use of resources and services.

Sustainable Growth & Development:
Summery: How different standards of living affect the environment
• Identify the differences in standards of living of highly developed and subsistence communities.
• Describe the economic and social impact of the discovery of minerals in South Africa (e.g. job creation, wealth creation, exploitation of cheap labour, migratory labour, health and safety hazards.

Entrepreneurial Knowledge & Skills:
Summery: Importance of natural resources to maintain sustainability
Explain how entrepreneurs combine labour (work), capital (money, machinery, tools), and natural resources (raw materials) to gain profit.

Technological processes and skills:
Summery: Focussing on people and the environment, solve a simple problem by identifying main design aspects and a scientific investigation.

Technological knowledge & understanding:
Summery: How to make stuff move using simple methods.
Report on the effect it has on the natural environment.

Technology, society and the environment:
Summery: How technology created inequalities between cultures
