RI 2022 Physics Planning Guidebook

2022 RAFFLES INSTITUTION PHYSICS DEPARTMENT Introduction to Planning Question Scheme of Assessment (from Syllabus 9749) Year 5 Planning question is part of the GCE A-level H2 Physics examination and it carries a weightage of 5%. Planning question will-be assessed as part of Paper 4 and you should complete it within 30 minutes. Your procedure must allow another person to conduct the experiment and evaluate the results of the experiment.

Candidates will not be permitted to refer to books and laboratory notebooks during the assessment. This paper will assess appropriate aspects of the following skill areas: • Planning (P) • Manipulation, measurement and observation (MMQ) • Presentation of data and obser✓ ations (PDQ) • Analysis, conclusions and evaluation (ACE) Note that the assessment of PDO and ACE may also include questions on data-analysis, which do not require practical equipment and apparatus. 1

2022 RAFFLES INSTITUTION PHYSICS DEPARTMENT Skills Requirements (from Syllabus 9749) Year5 Candidates should be able to define clearly the question/problem using appropriate knowledge and understanding. The plan should show a sense of coherence with a detailed sequence, providing a clear logical account of the experimental procedure to be followed. Candidates should describe how the data is used in order to reach a conclusion . The risks involved in the experiment should be assessed and precautions to keep these risks to a minimum should be described. Below is a brief summary of the requirements. (a) Defining the problem Students should be able·to • identify the independent and the dependent variables; • identify those variables that must be controlled; • give a clear precise statement as to what is being investigated. (b) Methods of data collection Students should be able to give a clear logical account of the experimental procedure to be followed, including a description of • how the independent variable is to be varied; • how the independent and the dependent variables are measured; • how the other variables are controlled; • the arrangement of the apparatus. (c) Method of analysis Students should be able to describe the main steps by which their data would be analysed in order to draw valid conclusions. This may well include the proposal of graphical methods to analyse data. (d) Safety considerations Students should be able to identify areas of risk and suggest suitable safety precautions to be taken. Question Structure The question is usually loosely structured and requires you to design an experiment to reach some conclusions. You may need to integrate knowledge from the
