Marking Guidelines Outcome Developing Elementary Substantial High PH11-9 Describes and explains events in terms of Newton’s Laws of Motion, the law of conservation of momentum and the law of conservation of energy Max. Marks 10 demonstrates limited knowledge of Newton’s laws of motion law, the law of conservation of momentum and law of conservation of energy Marks 1-3 states Newton’s laws of motion law, the law of conservation of momentum and law of conservation of energy without application Marks 4-5 applies Newton’s laws of motion to a static equilibrium situation or apply the conservation of mechanical energy to the quantitative analysis of motion Marks 6-8 apply Newton’s two laws of motion to a static equilibrium situation and apply the conservation of mechanical energy to the quantitative analysis of motion Marks 9-10 PH11/12-3 Conducts investigations to collect valid and reliable primary and secondary data and information Max. Marks 10 requires teacher assistance to conduct the investigation and to select appropriate equipment Marks 1-3 some suitable equipment is chosen safe practices are employed minimal identification of risks Marks 4-5 provides some evidence of validity reliability of data and sources safe practices are employed explanation of risks Marks 6-8 evaluates validity reliability of data and sources employs and evaluates safe work practices and manage risks uses appropriate technologies to ensure and evaluate accuracy data and source information is included Marks 9-10 PH11/12-4 Selects and processes appropriate qualitative and quantitative data and information using a range of appropriate media Max. Marks 7 data is disorganised and only one set of data from one experiment present Marks 1 selects data and information and represents them using a range of formats, digital technologies and appropriate media Marks 2-3 selects qualitative and quantitative data and information and represents them using a range of formats, digital technologies and appropriate media applies quantitative processes where appropriate discusses the reliability and validity of the data Marks 4-5 selects relevant qualitative and quantitative data and information and represents them using a range of formats, digital technologies and appropriate media applies quantitative processes where appropriate evaluates the reliability, validity and accuracy of the data Marks 6-7
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
