GCSE Syllabus - AQA


Mathematical and Other Requirements
7.4 Mathematical and Other Requirements The knowledge and skills in mathematics which are relevant to science and which are given below will not be exceeded in making assessments in this specification. Candidates will not be prevented from demonstrating achievement in science by mathematics which is excessively demanding.

• The four rules applied to whole numbers and decimals and to improper (and mixed) fractions
• Use of tables and charts
• Interpretation and use of graphs
• Drawing graphs from given data
• Reading, interpreting and drawing simple inferences from tables
• Vulgar and decimal fractions and percentages
• Scales
• Elementary ideas and application of common measures of rate
• Averages/means and the purpose for which they are used
• Substitution of numbers for words and letters in formulae
• Square and square root
• Conversion between vulgar and decimal fractions and percentages
• Expression of one quantity as a percentage of another; percentage change
• Drawing and interpreting of related graphs
• Idea of gradient
• Transformation of formulae
• Simple linear equations with one unknown
• Elementary ideas and applications of direct and inverse
proportion.

  Units, symbols and
nomenclature
Units, symbols and nomenclature used in examination papers will normally conform to the recommendations contained in the following:

• Signs, Symbols and Systematics . the ASE companion to 16-19 Science.
Association for Science Education (ASE), 2000. ISBN 0 86357 312 6
• Signs, Symbols and Systematics . the ASE companion to 5-16 Science.
Association for Science Education (ASE), 1995. ISBN 0 86357 232 4

Any generally accepted alternatives used by candidates will be given appropriate credit.
  Data sheet and formulae list

Data sheets and formulae lists are not included with the question papers for this specification.

Information of this kind should not be provided to candidates for use during examinations.

  Communication skills AQA takes care that candidates are not prevented from demonstrating achievement in science by the use of language in question papers which is inappropriately complex and hinders comprehension.
Similarly, while the assessment of communication is not a primary function of this specification, candidates are required to demonstrate scientific communication skills.

Scientific communication skills are specifically targeted by questions in the Investigative Skills Assignment (ISA) part of the centre-assessed unit. The externally set test for every ISA has a question in which the scoring of marks is in part dependent on skills such as presenting information, developing an argument and drawing a conclusion.

In addition, candidates will have difficulty in scoring the marks for science in any of the written assessments if they do not:
• ensure that text is legible and that spelling, punctuation and grammar are accurate so that meaning is clear
• present information in a form that suits its purpose
• use a suitable structure and style of writing.

In presenting their answers, they will also need to use scientific conventions (including chemical equations) and mathematical language (including formulae) accurately and appropriately to score all the available marks.
  ICT

The subject content of all GCSEs must require candidates to make effective use of ICT and provide, where appropriate, assessment opportunities for ICT. In science in the wider world ICT plays a crucial role, and teaching and learning in the GCSE Sciences should reflect this.

  Students should be given opportunities to:

• Use the internet (and other primary and secondary sources) to find information or data

• Use sensors and dataloggers to capture data in practical work

• Use spreadsheets or databases for data analysis, for modelling or to
explore patterns

• Use electronic resources e.g. software simulations, video clips

  Societal aspects of scientific evidence
A judgement or decision relating to social-scientific issues may not be based on evidence alone, as other societal factors may be relevant.

  Candidates should know and understand

• The credibility of the evidence is increased if a balanced account of the data is used rather than a selection from it which supports a particular pre-determined stance.
• Evidence must be scrutinised for any potential bias of the experimenter, such as funding sources or allegiances.
• Evidence can be accorded undue weight, or dismissed too lightly, simply because of its political significance. If the consequences of the evidence might provoke public or political disquiet, the evidence may be downplayed.
• The status of the experimenter may influence the weight placed on evidence; for instance, academic or professional status, experience and authority. It is more likely that the advice of an eminent scientist will be sought to help provide a solution to a problem than that of a scientist with less experience.
• Scientific knowledge gained through investigations can be the basis for technological developments.
• Scientific and technological developments offer different opportunities for exploitation to different groups of people.
• The uses of science and technology developments can raise ethical, social, economic and environmental issues.
• Decisions are made by individuals and by society on issues relating to science and technology. evidence

• Science can help us in many ways but it cannot supply all the answers. We are still finding out about things and developing our scientific knowledge. There are some questions that we cannot answer, maybe because we do not have enough reliable and valid evidence. For example, it is generally accepted that the extra carbon dioxide in the air (from burning fossil fuels) is linked to global warming, but some scientists think there is not sufficient evidence and that there are other factors involved.

• There are some questions that science cannot answer at all. These tend to be questions where beliefs and opinions are important or where we cannot collect reliable and valid scientific evidence. For example, science may be able to answer questions that start .How can we ... such as .How can we clone babies?. but questions starting .Should we ... such as .Should we clone babies? are for society to answer.
