Marking Guidelines: Outcome Developing Elementary Substantial High PH12-14 describes and analyses evidence for the properties of light and evaluates the implications of this evidence for modern theories of physics in the contemporary world Max. Marks 10 demonstrates limited knowledge of some properties of light states contributions made by one of the scientists Maxwell, Hertz, Huygens, Plank or Einstein Marks 1-3 describes some properties of light and describes some implications of the evidence for these properties describes contributions made by at least one of the scientists Maxwell, Hertz, Huygens, Plank or Einstein Marks 4-5 relates some properties of light and explains implications of the evidence for these properties relates contributions made by at least one of the scientists Maxwell, Hertz, Huygens, Plank or Einstein to the development of the current theories of light Marks 6-8 relates the properties of light and explains implications of the evidence for these properties explains the contributions made by at least one of the scientists Maxwell, Hertz, Huygens, Plank or Einstein to the development of the current theories of light Marks 9-10 PH11/12-2 designs and evaluates investigations in order to obtain primary and secondary data and information Maximum marks 5 identifies variables correctly chooses appropriate equipment Marks 1 chooses appropriate equipment to complete the practical investigation identifies variables correctly, including a number of controlled variables modifies the method as a result of testing Marks 2 chooses appropriate equipment to complete the practical investigation assesses risks justifies the selection of variables modifies the investigation in response to new evidence Marks 3 chooses appropriate equipment to complete the practical investigation assesses risks and considers a range of issues justifies and evaluates the selection of variables evaluates and modifies the investigation in response to new evidence Marks 4-5
PH11/12-5 Analyses and evaluates primary and secondary data and information Max. Marks 7 presents data with limited analysis Marks 1 identifies trends, patterns and relationships in data and information with limited analysis identifies errors, uncertainty and limitations in data Marks 2-3 describes trends, patterns and relationships in data and information describes error, uncertainty and limitations in data Marks 4-5 explains trends, patterns and relationships in data and information assesses error, uncertainty and limitations in data assesses the relevance, accuracy, validity and reliability of primary and secondary data and suggests improvements to investigations Marks 6-7 PH11/12-7 Communicates scientific understanding using suitable language and terminology for a specific audience or purpose Max. Marks 6 presents limited information shows limited understanding of the scientific concepts Marks 1 communicates basic information through descriptive texts uses some scientific terminology Marks 2 presents a well-organized report selects and uses suitable forms of digital, visual written and/or oral forms of communication selects and applies appropriate scientific notations, nomenclature and scientific language to communicate Marks 3-4 presents a sustained, logical and cohesive report supporting conclusions/ideas with evidence selects and uses effective forms of digital, visual written and/or oral forms of communication selects and applies appropriate scientific notations, nomenclature and scientific language to communicate in a variety of contexts Marks 5-6
