This early tale of biomimicry is based on historical fact. The Gobukson (or turtle ships) were known for their powerful design that included ironclad covering long before any western ships did. The story follows a young boy who observes a turtle in nature and then takes him to the emperor to illustrate his idea. This is a great book for budding inventors and could easily be paired with a maker's activity on boat building. The illustrations are intricate collages that lend the book a sense of warmth and solidity; you can almost feel the textures beneath your fingers. This really helps showcase the various design elements of the ship.
