Edexcel O Level Chemistry


 

Introduction
This syllabus provides a relevant course for all those who will end their study of chemistry at this stage, and lays a secure foundation for those who will continue their studies in this or related subjects.


Questions will be set in SI units except that pressure may be expressed in atmospheres (atm).
The syllabus has been designed so that teachers may be free to plan their own courses and explore some of the suggestions put forward in modem teaching programmes. It is essential that emphasis is laid on experimental work, preferably carried out by the pupils themselves. The syllabus stresses the unifying concepts and principles of chemistry, aims to minimize the summary work expected of pupils and should be used to emphasize the importance of chemistry for society and its power to contribute to the pattern of society in the future. As in the past, the style of examination questions will continue to change to take account of modem developments. The examination papers will test not only knowledge and understanding, but also the ability to use these to solve problems in chemistry and to devise experiments to test hypotheses.

Aims
The syllabus aims to:
1. illustrate the unifying patterns and themes of chemistry;
2. develop an appreciation of the usefulness and limitations of the procedures used by chemists and a logical approach to problem solving in a wider context;
3. emphasize the practical nature of chemistry, encourage practical and investigative
skills with correct and safe laboratory techniques, and make students aware of the
importance to scientific method of accurate experimental work and reporting;
4. develop students' ability to form hypotheses and to design experiments to test them;
5. illustrate the widespread importance of chemistry, and the way materials are used in the world;
6. show how the work of the chemist has social, industrial, technological, environmental and economic consequences for the community,


The examination will test:
1. Knowledge and understanding of:
(a) chemical facts and practical techniques together with the major applications and everyday uses of chemistry;
(b) chemical terminology, symbols and conventions;
(c) relevant physical quantities and their determination;
(d) physical and chemical principles, concepts, theories, definitions, laws, models, patterns and generalizations;
(e) social, economic, environmental and technological contributions, applications and implications of chemistry.

2. The ability of the candidate to:
(a) select suitable apparatus for carrying out experiments accurately and safely;
(b) organize, present and interpret data in the form of tables, graphs, symbols, diagrams or written statements;
(c) communicate scientific ideas, observations and arguments logically, concisely and sensibly;
(d) perform simple chemical calculations in familiar and unfamiliar situations;
(e) apply logical thinking to problem solving;
(t) devise safe, suitable, simple experiments and procedures for solving chemical problems;
(g) evaluate the results of an experiment, appreciating possible errors;
(h) select and use appropriate facts to illustrate models or hypotheses in the interpretation of observations;
(i) use experimental data, recognizing patterns in such data; form hypotheses and
deduce relationships, making decisions based on the examination of evidence and arguments;
(j) apply appropriate chemical principles, concepts, theories, definitions, laws, models and patterns to interpret, draw conclusions and make generalizations and predictions from chemical facts, observations and experimental data;
(k) appreciate the importance and implications of the social, economic, environmental and technological contributions and applications of chemistry.
