This fabulous Workout book is packed with clear and friendly practice covering everything Year 4 pupils need to know about Sound. 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 — all clearly laid out with plenty of space for writing answers. We’ve even included practical mini-projects to help them develop their “Working Scientifically” skills! Answers to every question are included on the pull-out centre pages, along with a handy A3 key-facts poster that children can colour in.
