Edexcel Combined Science Physics Paper 1 | Unit 4 Waves Revision Bundle | CP4a–CP4c

Save planning time and give students comprehensive, exam-focused revision with this complete Edexcel GCSE Combined Science Physics Paper 1 – Unit 4 Waves Revision Bundle. This bundle brings together the full set of ready-to-use revision resources for the CP4 Waves unit, covering both theory and practical skills across: - CP4a: Describing Waves - CP4b: Investigating Waves - CP4b: Wave Speed - CP4c: Investigating Refraction - CP4c: Refraction Each resource follows the same clear, consistent format and is designed to support retrieval practice, exam technique, calculation skills, core practical knowledge and independent revision. Across the bundle, students are given repeated exposure to a wide range of Edexcel-style command words and progressively more challenging questions, from short 1-mark retrieval items through to 6-mark extended responses. **What’s included across the bundle:** - 50 exam-style questions in total - Questions ranging from 1 to 6 marks - A broad range of Edexcel-style command words, including state, define, identify, give, describe, explain, compare, calculate, determine, analyse and evaluate - Detailed teacher mark schemes written in an Edexcel-style format - Clear student-friendly mark schemes for self-assessment, peer marking and independent study - Five 6-mark extended response questions - Three differentiated model answers for each extended response: Working Towards (Grade 4), Secure (Grade 7), Exemplary (Grade 9) - The bundle covers key Unit 4 content including: - transverse and longitudinal waves - amplitude, wavelength, frequency and period - wave speed calculations: v=fλ and v=x/t - equation rearrangement and unit conversion - measuring wave speed, frequency and wavelength - ripple tank investigations - practical uncertainty, accuracy and reliability - refraction - changes in wave speed and direction - the normal - angles of incidence and refraction - refraction of light and water waves - interpreting practical data - anomalous results - evaluating experimental methods The bundle also includes dedicated revision for the practical skills associated with Investigating Waves and Investigating Refraction, helping students prepare for exam questions that assess practical methods, measurements, variables, uncertainty and improvements. **Editable resources included** Editable file is provided so that questions, wording and formatting can be adapted to suit your classes. PDF print-ready versions are also included for ease. **Formatted in “Lexend” typeface for accessibility** Lexend’s design is grounded in cognitive science and research, making it a thoughtful choice for improving reading comprehension and creating accessible content. **Ready to print, ready to teach, and designed to reduce teacher workload while building students’ confidence with Edexcel exam-style questions, calculations, practical skills and extended scientific reasoning.** This complete Unit 4 set is ideal for end-of-unit revision, homework, intervention, cover lessons, retrieval practice, independent study, mock preparation, preparation for Edexcel Combined Science Physics Paper 1. Buying the complete bundle gives teachers a consistent, ready-to-use revision programme for the whole Waves unit while offering better value than purchasing each lesson resource separately.
