In Submarines and Submersibles, readers will be introduced to the engineering concepts that are involved in underwater vehicle design. This fact- and photo-filled book explains how submarine and submersibles are developed, how they work, and the different ways in which they are used. The Engineering Wonders series for grades 4–8 explores the ways engineers identify the needs to be met and/or problems to be solved and crated solutions through innovative design. Featuring 48 pages, this series takes a look at a variety of structural, technical, and transportation engineering and their applications
