Kids will learn how things they encounter every day operate by building their own models with this hands-on activity book. Projects include building a working model of the human hand’s muscles, bones, and tendons using drinking straws, tape, and string; using a pair of two-liter bottles and a length of rubber tubing to learn how a toilet flushes; and discovering how musical instruments make sounds by fashioning a harmonica, saxophone, drum, flute, or oboe. All devices are designed to use recycled or nearly free materials and common tools. Kids are encouraged to modify and improve the designs, or create an entirely new device using the concepts explored. Each project includes materials and tools lists, step-by-step instructions with photographs, a summary of the science concept demonstrated, and follow-up questions to gauge student understanding for use in the classroom.

Hobby motors—every workbench warrior has a few that have been pulled out of broken toys or rescued from old electronics kits. They’re cheap, available, and with Kinetic Contraptions, essential to build some ingenious moving creations. The two dozen contraptions found in this handy resource are assembled primarily from low-cost or recycled materials, batteries, and a single motor.
 
You’ll learn how to build vehicles that move across the land, over the sea, and through the air. Construct a hovercraft out of a Styrofoam plate, two corks, and binder clips. Build a double paddle-wheeler out of paint stirrers, plastic bottles, and disposable knives. Kinetic Contraptions even has “bizarro” devices, such as a waterless snow globe, a tornado in a bottle, and a mechanical bubble maker—no blowing required!
 
Each project is clearly explained through materials and tools lists, stepby- step instructions with photographs, and scientific background on the concepts being explored. Budding engineers will get experience working with tools, testing simple circuits, modifying and improving their designs, and building unique contraptions of their own with the skills they’ve developed.
