1. Mastering AO1 marks - Chemistry
2. What is AO1?Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures.You usually need to have learnt work to answer AO1 questionsRecall of facts simple e.g. test for oxygen gas complex e.g. explanation of Group 1 reactivity increasing down the groupSpecified practicals – methods, observationsSubstitution of values into equationsSometimes difficult to allocate – many grey areas because AO2 requires application of scientific ideas, processes, techniques and proceduresOn GCSE papers 40% of the marks are AO1
3. What is AO1?Double Award Unit 2 – Foundation Tier1 Periodic Table and properties of elements … AO1 and AO23(c) Substitution into an equation … AO14(a) Tectonic plate movement … AO1What about 4(b) and 4(c)?6 Fluoridation of water … AO18(b) Reaction of potassium and water … AO1 and AO2 Evolution of the atmosphere … AO1 … and balancing equationHow many of these marks are pure recall work that should be learnt?
4. Importance of learning workUseful to make students realise how important it is to learn their work.Activity – look at last summer’s Double Award Unit 5 FT paper and identify how many AO1 marks students could access just by learning their work
5. Unit 5 FTAll AO1 marks
6. Unit 5 FTAll AO1 marks
7. Unit 5 FTCorrection of errors 1 and 2 classed as AO1
8. Unit 5 FTAO1 marks
9. Unit 5 FTAO1 – but could be AO2?
10. Unit 5 FTDefinitely AO1
11. Unit 5 FTAO1AO1AO2AO2
12. Unit 5 FTBoth AO1
13. Unit 5 FTAO1AO1 and AO2
14. Unit 5 FTClassed as three marks each of AO1 and AO2
15. Unit 5 FTAbout 20 marks?
16. Revision and recall A weak area for many yearsRegular 5 minute tests e.g. flame test colours, testing for gases and negative ionsText tools on the resources part of the WJEC website could be useful in producing quick revision exercises e.g. arranging steps in a practical method in the correct order – www.resources.wjec.co.ukAnalysis of past papers in the weeks before exams … identify easy recall marks, topic areas and total number of marks available
