Part of a series of photographic activity books, this book includes projects on sound that aim to teach children the basic scientific concepts, encouraging them to take on new ideas and find out information for themselves. Each book introduces a basic topic, in this case sound and soundwaves, through projects that can be carried out at home using everyday items. Tricks and puzzles, and toys and models to make are also included. Neil Ardley is the co-winner of The Science Book Prize and The Times Educational Supplement Information Book Award for The Way Things Work.
