Grade 7: Eco Curriculum
• Natural hazards (e.g. drought, floods, earthquakes, volcanoes and tropical cyclones)
• simple explanations of how natural hazards occur – physical processes, climate change, poor environmental management
• management of risks and risk reduction – preventative measures (e.g. with regard to flooding, measures such as catchment management to improve the quality of rivers, vleis and wetlands, and reduce risk to human life and ecosystems).
Human evolution: rock art as an expression of hunter-gatherer society.
Influence of trade and moving frontiers had on the environment
The learner will be able to use inquiry skills to investigate the past and the present via archaeological, historical and old manuscripts, statistics.
Communicate knowledge and understanding by formulating arguments based on evidence from the sources either in debate, by producing longer pieces of historical writing, through artwork, graphics and drama; use technology where available.
E.g. resources in nature that tell us something of the past – rock paintings, iron age implements, remains of historic settlements, monuments and other.
Historical Knowledge and Understanding
The learner will be able to apply historical knowledge and understanding by making links between reasons for and results of key events and changes. He or she needs to explain why certain aspects of society in different contexts have not changed over time.
E.g. compare the natural environment of a servitude / indigenous culture with that of a capitalistic western rule.
The learner will be able to interpret aspects of history understanding that events might have been interpreted differently afterwards than while it was occurring and also because of the influence of different value systems and traditions.
E.g. how war could be seen as a means to an end for some (to lay hands on energy resources) and as completely negative by another (death, destruction).
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.
The Planet Earth and Beyond
Our place in Space
Summery: Regular changes are caused by the movement of the earth in space.
• Most objects in the solar system are in regular and predicted motion. The motions of the earth and moon explain such phenomena as the day, the year, the phases of the moon, and eclipses.
The Changing Earth
Summery: There exist resemblance’s between fossil records of pre-historic animals and those alive today. Possible causes for their extinction can be explored. Relate it to the looming environmental disaster.
• Many of the organisms in Africa’s fossil record cannot be easily classified into groups of organisms alive today, and some are found in places where present-day conditions would not be suitable for them. This is evidence that life and conditions on the surface of the earth have changed through time. (Links with Life and living)
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.
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.
