This CGP Workout book is packed with practice covering everything Year 4 (ages 8-9) pupils need to know about Sound - all clearly laid out with plenty of space for writing answers. There’s a range of questions for each topic, with a mixed section at the end of the book that tests children on everything they’ve learned. Practical mini-projects are also included to help them develop their scientific investigation skills. Answers to every question are included on the pull-out centre pages, along with a useful A3 poster that pupils can colour in.
