CAMBRIDGE IGCSE PHYSICS Cambridge International Certificate / Syllabus code 0625 Why choose Cambridge IGCSE Physics? Cambridge IGCSE Physics is accepted by universities and employers as proof of knowledge and understanding of physics. Successful candidates gain lifelong skills, including: confidence in a technological world, with an informed interest in scientific matters an understanding of how scientific theories and methods have developed, and continue to develop, as a result of groups and individuals working together an understanding that the study and practice of Physics/science are affected and limited by social, economic, technological, ethical and cultural factors an awareness that the application of Physics/science in everyday life may be both helpful and harmful to the individual, the community and the environment knowledge that science overcomes national boundaries and that the language of science, used correctly and thoroughly, is universal an understanding of the usefulness (and limitations) of scientific method, and its application in other subjects and in everyday life a concern for accuracy and precision an understanding of the importance of safe practice improved awareness of the importance of objectivity, integrity, enquiry, initiative and inventiveness an interest in, and care for, the environment an excellent foundation for advanced study in pure sciences, in applied science or in science-dependent vocational courses Assessment at a glance: Syllabus code 0625 Cambridge IGCSE Physics candidates are awarded grades ranging from A* to G. Candidates expected to achieve grades D, E, F or G, study the Core Curriculum only and are eligible for grades C to G. Candidates expected to achieve grade C or higher should study the Extended Curriculum, which comprises the Core and Supplement Curriculums; these candidates are eligible for all grades from A* to G. All candidates must enter for three papers. Aims The aims of the syllabus listed below describe the educational purposes of this examination. The aims of the syllabus are the same for all students and are not listed in order of priority. The aims are: 1. to provide a worthwhile educational experience for all candidates, through well designed studies of Experimental and practical science, whether or not they go on to study science beyond this level 2. to enable candidates to acquire sufficient understanding and knowledge to: become confident citizens in a technological world, to take or develop an informed interest in scientific matters recognise the usefulness, and limitations, of scientific method and to appreciate its applicability in other disciplines and in everyday life be suitably prepared for studies beyond IGCSE in pure sciences, in applied sciences or in science dependent vocational courses 3. to develop abilities and skills that are relevant to the study and practice of physics are useful in everyday life encourage safe practice encourage effective communication 4. to develop attitudes relevant to physics such as concern for accuracy and precision objectivity integrity enquiry initiative inventiveness 5. to stimulate interest in, and care for, the environment 6. to promote an awareness that scientific theories and methods have developed, and continue to develop, as a result of cooperative activities of groups and individuals the study and practice of science are subject to social, economic, technological, ethical and cultural influences and limitations the applications of science may be both beneficial and detrimental to the individual, the community and the environment science transcends national boundaries and that the language of science, correctly and rigorously applied, is universal Assessment objectives The three Assessment Objectives (AOs) in Cambridge IGCSE Physics are: A: Knowledge with understanding B: Handling information and problem solving C: Experimental skills and investigations A description of each assessment objective follows. A: Knowledge with understanding Candidates should be able to demonstrate knowledge and understanding of: 1. scientific phenomena, facts, laws, definitions, concepts, theories 2. scientific vocabulary, terminology, conventions (including symbols, quantities and units) 3. scientific instruments and apparatus, including techniques of operation and aspects of safety 4. scientific quantities and their determination 5. Scientific and technological applications with their social, economic and environmental implications. Curriculum content defines the factual material that candidates may be required to recall and explain. Candidates will also be asked questions which require them to apply this material to unfamiliar contexts and to apply knowledge from one area of the syllabus to knowledge of a different syllabus area. Questions testing these objectives will often begin with one of the following words: define, state, describe, explain (using your knowledge and understanding) or outline). B: Handling information and problem solving In words or using other written forms of presentation (e.g. symbolic, graphical and numerical), candidates should be able to: 1. locate, select, organise and present information from a variety of sources 2. translate information from one form to another 3. manipulate numerical and other data 4. 5. 6. 7. 8. use information to identify patterns, report trends and draw inferences present reasoned explanations of phenomena, patterns and relationships make predictions and hypotheses Solve problems, including some of a quantitative nature. Questions testing these skills may be based on information that is unfamiliar to candidates, requiring them to apply the principles and concepts from the syllabus to a new situation, in a logical, reasoned or deductive way. Questions testing these skills will often begin with one of the following words: predict, suggest, calculate or determine. C: Experimental skills and investigations Candidates should be able to: 1. know how to use techniques, apparatus, and materials (including following a sequence of instructions, where appropriate) 2. make and record observations and measurements 3. interpret and evaluate experimental observations and data 4. Plan investigations, evaluate methods and suggest possible improvements (including the selection of techniques, apparatus and materials). Assessment objectives and their weighting in the components Curriculum themes The curriculum is divided into five themes which have been designed to develop an understanding of the theory and practical applications of physics in real life situations: 1. 2. 3. 4. 5. General Physics Thermal Physics Properties of Waves, including Light and Sound Electricity and Magnetism Atomic Physics The full IGCSE Physics syllabus can be downloaded from the CIE website. www.cie.org.uk/qualifications/academic/middlesec/igcse/subjects Other information Mathematical requirements Candidates may use calculators in all parts of the exam. Candidates should be able to: add, subtract, multiply and divide use averages, decimals, fractions, percentages, ratios and reciprocals recognise and use standard notation use direct and inverse proportion use positive, whole number indices draw charts and graphs from given data interpret charts and graphs choose suitable scales and axes for graphs make approximate evaluations of numerical expressions recognise and use the relationship between length, surface area and volume and their units on metric scales use usual mathematical instruments (ruler, compasses, protractor, set square) understand the meaning of angle, curve, circle, radius, diameter, square, parallelogram, rectangle and diagonal solve equations of the form x = yz for any one term when the other two are known Recognise and use points of the compass (N, S, E, W).
