IB19 05_0846_02/3RP © UCLES 2019 [Turn over Cambridge Assessment International Education Cambridge Primary Checkpoint SCIENCE 0846/02 Paper 2 April 2019 MARK SCHEME Maximum Mark: 50 Published This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Markers were instructed to award marks. It does not indicate the details of the discussions that took place at an Markers’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the End of Series Report. Cambridge will not enter into discussions about these mark schemes.
