To satisfy the Common Practical Assessment Criteria (CPACs) for A-level physics, you need to demonstrate competence in the following areas: following written procedures; applying investigative approaches and methods; safely using equipment and materials; making and recording observations; and researching, planning and reporting (including data analysis).
The awarding bodies for A-level physics require or suggest a number of practical activities that will allow you to satisfy the CPACs. Among other requirements, these expect you to be able to use appropriate analogue apparatus to record a range of measurements, which include length/distance, temperature, pressure, force, angle and volume. An investigation into Boyle’s and Charles’s laws enables you to measure temperature, pressure and volume, and to analyse your results, and can be used as a core or required practical.
