Extensive research through lesson observations, teacher interviews and work with our online teacher community (the Cambridge Panel) means that this flexible range of resources meets the real teaching needs of the science classroom. This write-in workbook contains step-by-step guided investigations and practice questions for Cambridge International AS & A Level Chemistry teachers and students. Through practical investigation, it provides opportunities to develop skills– planning, identifying equipment, creating hypotheses, recording results, analysing data, and evaluating. The workbook is ideal for teachers who find running practical experiments difficult due to lack of time, resources or support. Sample data – if students can’t do the experiments themselves – and answers to the questions are in the teacher’s guide.
