OCR 2015GCSE (9–1) in Physics A (Gateway Science)All GCSE (9–1) qualifications offered by OCRare accredited by Ofqual, the Regulator forqualifications offered in England. Theaccreditation number for OCR’s GCSE (9–1)in Physics A (Gateway Science) isQNXXXXXX.3

1b. Why choose an OCR GCSE (9–1) in Physics A (GatewayScience)?We appreciate that one size doesn’t fit all sowe offer two suites of qualifications in eachscience:Physics A – Provides a flexible approach toteaching. The specification is divided intotopics, each covering different key conceptsof physics. Teaching of practical skills isintegrated with the theoretical topics and theyare assessed through the written papers.Our new GCSE (9–1) in Physics A (GatewayScience) qualification builds on our existingpopular course. We’ve based theredevelopment of our GCSE sciences on anunderstanding of what works well in centreslarge and small. We’ve undertaken asignificant amount of consultation through ourscience forums (which includerepresentatives from learned societies, HE,teaching and industry) and through focusgroups with teachers.The content is clear and logically laid out forboth existing centres and those new to OCR,with assessment models that arestraightforward to administer. We haveworked closely with teachers to provide highquality support materials to guide you throughthe new qualifications.DraftPhysics B – Learners study physics using anarrative-based approach. Ideas areintroduced within relevant and interestingsettings which help learners to anchor theirconceptual knowledge of the range ofphysical topics required at GCSE level.Practical skills are embedded within thespecification and learners are expected tocarry out practical work in preparation for awritten examination that will specifically testthese skills.and other stakeholders with the aim ofincluding up-to-date relevant content within aframework that is interesting to teach andadminister within all centres (large andsmall).All of our specifications have been developedwith subject and teaching experts. We haveworked in close consultation with teachersAims and learning outcomesOCR’s GCSE (9–1) in Physics A (GatewayScience) will encourage learners to: develop scientific knowledge andconceptual understanding of physics develop understanding of the nature,processes and methods of science,through different types of scientificenquiries that help them to answerscientific questions about the worldaround them4 develop and learn to applyobservational, practical, modelling,enquiry and problem-solving skills, bothin the laboratory, in the field and inother learning environments develop their ability to evaluate claimsbased on science through criticalanalysis of the methodology, evidenceand conclusions, both qualitatively andquantitatively.

2b. Content of GCSE (9–1) in Physics A (Gateway Science) (J249)The GCSE (9–1) in Physics A (GatewayScience) specification content is divided intoeight teaching topics and each topic is furtherdivided into key sub-topics. Each sub-topic isintroduced with a short summary text,followed by the underlying knowledge andunderstanding learners should be familiarwith and common misconceptions associatedwith the topic.The ‘Assessable content’ is shown by thepurple highlighting: Assessablemathematical learning outcomes,Learning outcomes and To include.The Assessable mathematicallearning outcomes highlight the mathslearning outcomes which will beassessed in an examination on thatparticular topic.Maths: the mathematical skillsrequirements in Appendix 5g can beassessed throughout the examination.These are referenced in the Mathscolumn by the prefix M to link themathematical skills required for GCSE(9–1) in Physics A (Gateway Science)to examples of physics content wherethose mathematical skills could belinked to learning. Working scientifically: references toworking scientifically (Appendix 5f) areincluded in the Working scientificallycolumn to highlight opportunities toencourage a wider understanding ofscience.ft The Learning outcomes may all beassessed in the examinations. Thestatements in bold are intended forhigher tier only. Therefore, higher tierlearners need to be taught the entirespecification. Foundation tier learnersmust be taught the entire specification,apart from the statements in bold. The To include column is included toprovide further advice on delivery.Practical/research: OCR has split thelist of apparatus and techniquesrequirements from the Department forEducation ‘GCSE subject content’ intoeight Practical Activity Groups or PAGs.The table in Appendix 5i illustrates theskills required for each PAG and anexample practical that may be used tocontribute to the PAG. Within thespecification there are a number ofsuggested practicals that are illustratedin the ‘Opportunities for’ column, whichcount towards each PAG. We areexpecting that centres do a wide rangeof practical activities during the course.These can be the ones illustrated in thespecification or can be practicals thatare devised by the centre. Activities canrange from whole investigations tosimple starters and plenaries.Dra The ‘Opportunities for’ is divided into threecolumns: Maths, Working scientifically andPractical/research. Items that are containedwithin these columns will not be directlyassessed, but are intended as a starting pointfor lesson planning.The specification has been designed to beco-teachable with the standalone GCSE (9–1) in Combined Science A (GatewayScience) qualification.A summary of the content for the GCSE (9–1)in Physics A (Gateway Science) course is onthe next page.8 OCR 2015GCSE (9–1) in Physics A (Gateway Science)

2c. Content of topics P1 to P8Topic P1: MatterP1.1 The particle modelatoms, molecules and compounds. Learners should understand howdensity can be affected by the state materials are in.Common misconceptionsLearners commonly confuse the different types of particles (subatomicparticles, atoms and molecules) which can be addressed through theteaching of this topic. They commonly misunderstand the conversionsbetween different units used in the measurement of volume.DraftSummaryKnowledge and understanding of the particle nature of matter isfundamental to Physics. Learners need to have an appreciation of matterin its different forms, they must also be aware of the subatomic particles,their relative charges, masses and positions inside the atom. Thestructure and nature of atoms are essential to the further understanding ofphysics. The knowledge of subatomic particles is needed to explainmany phenomena, for example those involving charge and transfer ofcharges, as well as radioactivity. (Much of this content overlaps with thatin the Chemistry content within Combined Science).Underlying knowledge and understandingLearners should be aware of a simple atomic model, and that atoms areexamples of particles. They should also know the difference betweenReferencePM1.1i10TieringStatements shown in bold type will only be tested in the Higher tierpapers.

Understanding of the relationshipbetween the states of matter helps to explain different types of everydayphysical changes that we see around us.TieringStatements shown in bold type will only be tested in the Higher tierpapers. All other statements will be assessed in both Foundation andHigher tier papers.ReferencePM1.2iPM1.2iiDraftUnderlying knowledge and understandingLearners should be familiar with the structure of matter and the similaritiesand differences between solids, liquids and gases. They should have asimple idea of the particle model and be able to use it to model changesin particle behaviour during changes of state. Learners should be awareof the effect of temperature in the motion and spacing of particles and anunderstanding that energy can be stored internally by materials.Common misconceptionsLearners commonly carry misconceptions about matter; assuming atomsare always synonymous with particles. Learners also struggle to explainwhat is between the particles, instinctively ‘filling’ the gaps with ‘air’ or‘vapour’. They often struggle to visualise the 3 dimensional arrangementof particles in all states of matter. Learners can find it challenging tounderstand how kinetic theory applies to heating materials and how touse the term temperature correctly, regularly confusing the termstemperature and heat.Assessable mathematical learning outcomesMathematical skillsapply: change in thermal energy m x specific heat capacity x change intemperatureM1a, M3b, M3c, M3dapply: thermal energy for a change in state m x specific latent heatM1a, M3b, M3c, M3dAssessable contentLearning outcomesP1.2adescribe how mass is conservedwhen substances melt, freeze,evaporate, condense or sublimateTo includeMathsOpportunities forWorkingscientificallyWS1.3a,WS1.3e,WS1.4a,WS2a, WS2cPractical/researchUse of a data logger to recordchange in state and mass atdifferent temperatures.
