Chemistry GCSE practicals guide for England

From September 2016 there are new practical requirements for GCSE science in England and Wales.

Are you concerned about introducing one of the new experimental techniques? or just looking for an interesting way to approach a particular topic - in either case this document is for you.

To support the teaching of chemistry practical work, we have mapped the GCSE chemistry specifications from AQA, OCREdexcel, and Eduqas to practical activities and linked these to Learn Chemistry resources

Table 1 - Required practical apparatus and techniques for chemistry as specified by the English National Curriculum:

 

Apparatus and techniques

1

Use of appropriate apparatus to make and record a range of measurements accurately, including mass, time, temperature, and volume of liquids and gases.

2

Safe use of appropriate heating devices and techniques, including use of a Bunsen burner and a water bath or electric heater.

3

Use of appropriate apparatus and techniques for conducting and monitoring chemical reactions, including appropriate reagents and/or techniques for the measurement of pH in different situations.

4

Safe use of a range of equipment to purify and/or separate chemical mixtures, including evaporation, filtration, crystallisation, chromatography, and distillation.

5

Making and recording of appropriate observations during chemical reactions, including changes in temperature and the measurement of rates of reaction by a variety of methods such as the production of gas or a colour change.

6

Safe use and careful handling of gases, liquids and solids, including careful mixing of reagents under controlled conditions, using appropriate apparatus to explore chemical changes and/or products.

7

Use of appropriate apparatus and techniques to draw, set up and use electrochemical cells for separation and production of elements and compounds.

8

Use of appropriate qualitative reagents and techniques to analyse and identify unknown samples or products, including gas tests, flames tests, precipitation reactions, and the determination of concentrations of strong acids and strong alkalis.

NB: Practical technique 8 is only required in the single sciences

Single science chemistry:
In England, for the single sciences, students need to complete 8 experiments in each of Biology, Chemistry and Physics.

Chemistry GCSE practicals guide for Wales.

Specified practical work in the new Chemistry GCSEs to be taught from September 2016

Practical skills as part of the WJEC science GCSEs

1) Development of scientific thinking
• Understand how scientific methods and theories develop over time
• Use a variety of models such as representational, spatial, descriptive, computational and mathematical to solve problems, make predictions and to develop scientific explanations and understanding of familiar and unfamiliar facts
• Appreciate the power and limitations of science and consider any ethical issues which may arise
• Explain every day and technological applications of science; evaluate associated personal, social, economic and environmental implications; and make decisions based on the evaluation of evidence and arguments
• Evaluate risks both in practical science and the wider societal context, including perception of risk in relation to data and consequences
• Recognise the importance of peer review of results and of communicating results to a range of audiences.

2) Experimental skills and strategies
• Use scientific theories and explanations to develop hypotheses
• Plan experiments or devise procedures to make observations, produce or characterise a substance, test hypotheses, check data or explore phenomena
• Apply knowledge of a range of techniques, instruments, apparatus, and materials to select those appropriate to the experiment
• Carry out experiments appropriately having due regard to the correct manipulation of apparatus, the accuracy of measurements and health and safety considerations
• Make and record observations and measurements using a range of apparatus and methods
• Evaluate methods and suggest possible improvements and further investigations

3) Analysis and evaluation
Apply the cycle of collecting, presenting and analysing data, including:
• Presenting observations and other data using appropriate methods
• Translating data from one form to another
• Carrying out and representing mathematical analysis
• Representing distributions of results and make estimations of uncertainty
• Interpreting observations and other data (presented in verbal, diagrammatic, graphical, symbolic or numerical form), including identifying patterns and trends, making inferences and drawing conclusions
• Presenting reasoned explanations including relating data to hypotheses
• Being objective, evaluating data in terms of accuracy, precision, repeatability and reproducibility and identifying potential sources of random and systematic error
• Communicating the scientific rationale for investigations, methods used, findings and reasoned conclusions through paper-based and electronic reports and presentations using verbal, diagrammatic, graphical, numerical and symbolic forms.

4) Scientific vocabulary, quantities, units, symbols and nomenclature
• Use scientific vocabulary, terminology and definitions
• Recognise the importance of scientific quantities and understand how they are determined
• Use SI units (e.g. kg, g, mg; km, m, mm; kJ, J) and IUPAC chemical nomenclature unless inappropriate
• Use prefixes and powers of ten for orders of magnitude (e.g. tera, giga, mega, kilo, centi, milli, micro and nano)
• Interconvert units
• Use an appropriate number of significant figures in calculation.

NB: All the Learn Chemistry resources mapped below are intended to be used to support teaching of GCSE science, rather than to provide direction on teaching or schemes of work

In Wales, students studying separate science GCSEs must experience 10 specified practicals, which may be assessed in examinations. For double award science GCSEs, students must experience 21 specified practicals (seven for each science discipline). Practical skill is mainly assessed in a separate practical assessment carried out in schools and externally marked by WJEC.
In applied science GCSE, single award students must experience 10 specified practicals, of which four are related to chemistry. Double award students must experience 21 specified practicals, of which eight relate to chemistry. Practical skills are mainly assessed in a separate practical assessment carried out in schools and externally marked by WJEC.
