Beskrivelse
A working kaleidoscope, a marble runway, a robotic hand, a flying rubber-band airplane, and a flapping prehistoric bird are just some of the ingenious projects that can be constructed from cardboard boxes, sheets, and tubes -- and that are sure to excite and engage kids who love to build, tinker, and invent. With easy-to-follow, step-by-step photographic instructions, young learners curious about how things work are encouraged to exercise their engineering smarts, expand their 3-D thinking, and learn cool building techniques. Ideas for customizing and tinkering make this the perfect book for school science fairs, family projects, and classroom collaboration.
