The syllabus for Cambridge IGCSE Environmental Management (0680) has been broken down into teaching units with suggested teaching activities and learning resources to use in the classroom. This scheme of work, like any other, is meant to be a guideline, offering advice, tips and ideas. It can never be complete but hopefully provides teachers with a basis to plan their lessons. It covers the minimum required for the Cambridge IGCSE course but also adds enhancement and development ideas on topics. It does not take into account that different schools take different amounts of time to cover the Cambridge IGCSE course. Recommended prior knowledge Learners beginning this course are not expected to have previously studied Environmental Management. Outline Whole class (W), group work (G) and individual activities (I) are indicated throughout this scheme of work. The activities in the scheme of work are only suggestions and the syllabus should always be referred to. There are also many other useful activities to be found in the materials referred to in the learning resource column. Opportunities for differentiation are indicated as basic (B) and challenging (C); there is the potential for differentiation by resource, grouping, expected level of outcome, and degree of support by teacher, throughout the scheme of work. Timings for activities and feedback are left to the judgment of the teacher, according to the level of the learners and size of the class. Length of time allocated to a task is another possible area for differentiation The units within the scheme of work are: Unit 1: Unit 2: Unit 3: Unit 4: Lithosphere: rocks and minerals, energy, tectonic activity, soils Hydrosphere: water on the land, the oceans Atmosphere: atmosphere and air pollution, climate and agriculture, climatic hazards Biosphere: ecosystems, biomes and types of vegetation, human activities: impacts and strategies for conservation, population and economic development Suggested teaching order The syllabus does not prescribe a particular sequence of study and this scheme of work is just one suggested pathway.

V1 4Y05 Cambridge IGCSE Environmental Management (0680) – from 2014–2017 4 Scheme of work – Cambridge IGCSE® Environmental Management (0680) Unit 1: Lithosphere Recommended prior knowledge Learners beginning this course are not expected to have previously studied Environmental Management. A good general knowledge, particularly of events in the news such as earthquakes and volcanic eruptions, is recommended. Context This unit provides information about the structure of the Earth and the natural processes that operate on it. Knowledge of the Earth's natural resources is useful to a full understanding of content in later units; for example, elements of knowledge of soils is useful to the agricultural parts of Unit 3, and managing the land sections in Unit 4. Case studies, practical tasks and investigations are included where appropriate. Case studies can be particularly useful for the teaching of several aspects of the syllabus through a specific environmental management example. Outline The Lithosphere unit is separated into four topic areas: Rocks and minerals Energy Tectonic activity Soils Opportunities are provided for learners to develop practical skills, such as drawing graphs, diagrams, labelled sketches and sketch maps. These can be used again and extended in later units. Learners are encouraged to keep up to date with topical events and to choose examples from the home region or home country whenever possible. Teaching time Based on a total time allocation of approximately 130 contact hours for this Cambridge IGCSE course, it is recommended that this unit should take about 30 hours.

A good general knowledge, particularly of events in the news, such as the importance of supplies of fresh water, the role of dirty water in spreading diseases and perpetuating poverty in the developing world and an awareness of increasing concern about the over-exploitation of marine resources is recommended. Context This unit provides information about the water cycle, flooding, drought and ocean currents which link with the later atmosphere unit. A similar link exists between water cycle and ecosystems, before the latter becomes a more specialised study in the biosphere unit. Case studies are suggested; these can be replaced with examples which are more local to the Centre, or with those that are more topical at the time of study. Outline This unit is separated into two topic areas: Water on the land The oceans Opportunities for learners to re-use and extend their practical skills will continue to be suggested. Learners should be encouraged to keep up to date with topical events, such as floods, droughts, oil spills and continuing attempts to find a cure for malaria, a major killer of people living in the tropics. Teaching time Based on a total time allocation of approximately 130 contact hours for this Cambridge IGCSE course, it is recommended that this unit should take about 30 hours.

A good general knowledge, particularly of events in the news such as deforestation and habitat loss, reduced biodiversity and land degradation, the use of genetically modified crops, the widening development gap between rich and poor and rapid urbanisation, is recommended. Context This unit provides information about ecosystems, biomes, population and human activities. It is the largest of the four units, with considerable variety in content. Case studies and practical tasks are included where appropriate. Opportunities for local investigations of plant and animal habitats are also given, for an ecosystem, vegetation succession, food chain and food web, Outline This unit is separated into three topic areas: Ecosystems, biomes and types of vegetation Human activities: impacts and strategies for conservation Population and economic development Opportunities are provided for learners to use and further develop their practical skills, such as drawing graphs, diagrams and labelled sketches. Teaching time Based on a total time allocation of approximately 130 contact hours for this Cambridge IGCSE course, it is recommended that this unit should take about 40 hours.
