For first examination from 2022, these resources meet the real needs of the physics classroom. This practical write-in workbook is the perfect companion for the coursebook. It contains step-by-step guided investigations and practice questions for Cambridge International AS & A Level Physics 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 resource.
