Grade 9: Eco Curriculum


 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)

Effect of war and the conflict over territory on the environment.



Life and Living

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)
LIFE ORIENTATION SPECIFIC THEME: Take care of your environment; take care of yourself


Technology, society and the environment:
Summery: Improved methods to ensure continued existence without degradation of environment or marginalization

Indigenous technology and culture
Explore, compare and explain how different cultures in different parts of the world have effectively adapted technological solutions for optimal usefulness.

Impact of Technology
Recognise and identify the impact of technological developments on the quality of people’s lives and on the environment in which they live, and suggest strategies for reducing any undesirable effects.
