Environment 7: Grade 09

Grade 9: Eco Curriculum

SOCIAL SCIENCES

Geography
• Development issues:
• approaches to development:
 concepts of developing, developed, sustainable development and sustainability
 applicability to your country and elsewhere
• the role of science and technology:
 effect on development and its effect on the environment
 the Green Revolution
 modification of crops
 use of appropriate technology
• Sustainable use of resources:
• principles of Agenda 21, such as the need for everybody to participate in the management of resources
• the dependence of all people on natural resources for their livelihood and survival
• the need for all our actions to ensure future sustainability
• the need for everybody to be actively involved in addressing environmental problems (e.g. pollution, waste disposal)
• Social and environmental conflicts in your country:
• comparison with other countries in Africa and elsewhere
• the role of power, control and discrimination (including racism and xenophobia) in shaping access to and use of resources such as land, food, water, housing and jobs
• use of relevant case studies

 

NATURAL SCIENCES

Life and Living

Life processes and healthy living:
Summery: Without fertile soil, plants cannot produce the nutrients required for healthy living. This natural resource should be protected.
• Green plants use energy from the sun, water and carbon dioxide from the air to make food by photosynthesis. This chemical reaction is central to the survival of all organisms living on earth.
• Animals including humans require protein, fat, carbohydrates, minerals, vitamins and water. Food taken in is absorbed by the body via the intestine. Surplus food is stored as fat or carbohydrate.

Interactions in Environments:
Summery: As humans we have the cognitive ability to make choices and should by all means encourage the well-being of all elements in the system.
• Pollution interferes with natural processes that maintain the interdependencies and diversity of an ecosystem.
• Many biological changes, including decomposition and recycling of matter in ecosystems and human diseases, are caused by invisibly small, quickly reproducing organisms.

Bio-diversity, Change and Continuity:
Summery: As humans we have the cognitive ability to make choices to understand this co-existence and should by all means encourage the well-being of all elements in the system.
• Human activities such as the introduction of alien species, habitat destruction, population growth, pollution and over consumption, result in the loss of bio-diversity. This becomes evident when more species become endangered or ultimately extinct.
• Extinction also occur through natural events. Mass extinctions have occurred in the past, suggesting that huge changes to environments have occurred. However these changes occurred very slowly, compared to the fast rate at which humans can destroy plant and animal species. (Links with soil in Planet Earth and Beyond)
The Planet Earth and Beyond
Atmosphere and weather
Summery: As human activities has an effect on the gaseous composition and weather globally, we should care of how we apply development.
• Human activities and natural events can slightly change the composition and temperature of the atmosphere. Some effects of these small changes may be changes in annual weather patterns and long-term changes in rainfall and climate.

The Changing Earth
Summery: In pre-historic history minerals have been deposited for various reasons at different places across the globe; as fossil fuels were formed over millions of years. Point out the harmful effects of fossil fuel and mining on the environment.
• Fossil fuels such as coal, gas and oil are the remains of plants and animals that were buried and fossilized at high pressures. These fuels are not renewable in our lifetimes. (Links with Energy and Change)
• Mining is a major industry in Africa, with local examples in all the nine provinces. It is important in terms of the supply of coal for energy, essential raw materials for other industries, employment and earnings for the country. A great number of other industries depend on the mining industry. Legislation controls mining with regard to safety and environmental effects.

 

LIFE ORIENTATION SPECIFIC THEME: Take care of your environment; take care of yourself
In the National Curriculum Framework no theory, but only practical application has been identified for this learning area.
