NATURAL SCIENCES

Life and Living

Interactions in Environments:
Summery: A good bio-diversity is key to a healthy co-existence between living things.
• An ecosystem maintains numerous food webs and competition for food among different individuals and populations. Your country has certain ecosystems which have exceptional bio-diversity.  All uses of these areas must be based on principles for sustainable development.

Bio-diversity, Change and Continuity:
Summery: Variation allows us to classify the various kinds of life on earth. The bigger the variety of elements in a particular environment, the stronger the chance for it to survive.
• Variation in human biological characteristics such as skin colour, height and so on have been used to categorise groups of people. These biological differences do not indicate differences in innate abilities of the groups concerned. Therefor such categorisation of groups by biological differences is neither scientifically valid nor exact; it is a social construct.
• Bio-diversity enables ecosystems to sustain life and recover from changes to the environment. Loss of bio-diversity seriously affects the capacity of ecosystems and the earth to sustain life. Classification is a means to organise the great diversity of organisms and make them easier to study. The two main categories of animals are the vertebrates and invertebrates, and among vertebrates the five classes are amphibians, birds, fish, reptiles and mammals.
ECONOMIC MANAGEMENT

The Economic Cycle:
Summery: Impact that wants has on environment and community
Explain needs and wants and how the differences between them impact on communities and the environment.
TECHNOLOGY THEME

Technological processes and skills:
Summery: Design a product to fulfill a need in the community taking into account safety and environmental considerations.
• Investigate the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a local context.
• Examine existing products relevant to the problem, situation or need based on the following key aspects of design:
• environment;
• List product and design specifications and constraints for a solution to a given problem, need or opportunity based on some of the design key words:
• Environment: where the product will be used or made, impact on the environment;
