GCSE Chemistry How to answer 6 mark LOR – J258-04 2018 Example: J258 04 June 18, Q7a Task 1: Read this question 7. A new type of salt for using food is called ‘Lo-So salt’. Nina wants to find out what elements ‘Lo-Salt salt’ contains. She does some experiments to find the emission spectra of some compounds of Group 1 elements. She also does an experiment to find the emission spectrum of ‘Lo-Salt salt’. She puts small samples of each element and the salt in a spectroscopy machine and looks at the print- out of results. Here are Nina’s results. (a) Nina says that she thinks she needs to do further experiments to identify all the elements in ‘Lo- So salt’. State which elements ‘Lo-So salt’ does and does not contain, giving your reasons, and describe what further experiments Nina needs to do to identify all the elements in ‘Lo-So salt’.

Read the part of the question that tells you what to do…. Underline parts of the question that you need to include when you write your answer. Task 2: What levels are these answers? Look again at the question. The ‘important things to do’ have been underlined: State which elements ‘Lo-So salt’ does and does not contain, giving your reasons , and describe what further experiments Nina needs to do to identify all the elements in ‘Lo-So salt’. A ‘good’ answer (a Level 3 answer ) will answer ALL parts of the question so will …. Identify which elements are and are not present Give reasons for the identification of elements using the information given Describe the further experiments needed (at least one) Answers at level 2 and level 1 will only answer some parts of the question. Look at these five examples of candidate answers In your group, decide whether you think each answer is a ‘level 1’ or a ‘level 2’ or a ‘level 3’ answer. You don’t need a mark scheme to do this, just use your judgement, based on what the question is asking. Justify your decisions by… Underlining parts of the answers that you ‘like’ and work out which part of the question the answer links to. Making notes on the answer to say what you think is ‘missing’. Version 1 2 © OCR 2019 ‘State which elements ‘Lo-So salt’ does and does not contain, giving your reasons, and describe what further experiments Nina needs to do to identify all the elements in ‘Lo-So salt’.’
Answer 1 State which elements ‘Lo-So salt’ does and does not contain, giving your reasons, and describe what further experiments Nina needs to do to identify all the elements in ‘Lo-So salt’
