Combining fun and interactive activities, this guide will have kids captivated for hours constructing fantastic racing cars with the basics of only rubber bands, cardboard, and glue. These simple instructions with templates allow budding engineers to gain hands-on experience as they learn not only how to build a basic racer, but how to make modifications such as aluminum foil axle bearings, steering mechanisms, hinges, cam shafts, and wheels made out of old CDs. This helpful resource has step-by-step instructions for making a basic rubber-band model, a railroad push-car, and a high-speed racer. Other unique projects include Oscar the Laughing Clown, which has a jaw mechanism that opens and closes when it moves, and Spot the Dog, which has a moving tail. Children can even learn how to build a rubber band car big enough for a human. Exploring wheels, bearings, and friction, kids will learn not only how to make speedy racers but also the science that makes the process work.

Presents step-by-step instructions for building a variety of electronic devices, including a talking alarm, a moving eyeball painting, and a flashlight without batteries.

"Provides children with instructions and tips on how to build a variety of vehicles"--

3D printers have revolutionized the worlds of manufacturing, design, and art. But how does a person with little or no computer design experience create an object to print? The best way to learn is through hands-on experience. Professional engineer Mike Rigsby leads readers step-by-step through fourteen simple toy projects, each illustrated with screen caps of Autodesk 123D Design, the most common free 3D software available. The projects are later described using Sketchup, another free popular software package. The toy projects in A Beginner's Guide to 3D Printing start simple—a domino, nothing more than an extruded rectangle, a rectangular block. But soon you will be creating jewel boxes with lids, a baking powder submarine, interchangeable panels for a design-it-yourself miniature house, a simple train with expandable track, a multipiece airplane, a working paddleboat, and a rubber band&–powered car. Finally, you will design, print, and assemble a Little Clicker, a noise making push toy with froggy eyes. Once trained in the basics, you will be able to embark on even more elaborate designs of your own creation.

Here's help in selecting current, nonfiction books that will get boys excited about reading. Enticing boys to read is still a hot topic. With chapters like "Disasters and Mysteries," "Gross and Disgusting," "Machines and the Military," and "Prehistoric Creatures," Gotcha Again for Guys!: More Nonfiction Books to Get Boys Excited about Reading is a treasure trove of recent nonfiction books that will interest boys in grades 3-8. This sixth entry in Baxter and Kochel's Gotcha series covers books published between 2007 and 2009, with a few oldies-but-goodies also included. The book is organized into 12 thematic chapters, each of which offers booktalks for a select number of titles, followed by a list of other high-interest, well-reviewed titles that correspond with the chapter's topic. Features new to this volume include numerous booklists to be copied and saved, as well as profiles of new and innovative nonfiction authors writing for this age group. In addition, the book features interviews with seven male authors of nonfiction books for boys.

Boys' Life is the official youth magazine for the Boy Scouts of America. Published since 1911, it contains a proven mix of news, nature, sports, history, fiction, science, comics, and Scouting.

Though students aren’t yet old enough to drive, that doesn’t mean they can’t satisfy their need for speed. Author and physics teacher Bobby Mercer will show readers 25 easy-to-build racecars that can be driven both indoors and out. Better still, each of these vehicles is constructed for little or no cost using recycled and repurposed materials. The Racecar Book will teach readers how to use mousetraps, rubber bands, chemical reactions, gravity, and air pressure to power these fast-moving cars. They will learn how to turn a potato chip can, a rubber band, and weights into a Chip-Can Dancer, or retrofit a toy car with a toy plane propeller to make an air-powered Prop Car. An effervescent tablet in a small canister makes an impressive rocket engine for a Mini Pop Car, and old CDs, a small cardboard food box, and drinking straws become a Mac-n-Cheese Roller. Every hands-on project contains a materials list and detailed step-by-step instructions. Mercer also includes explanations of the science behind each racecar, including concepts such as friction, Newton’s laws of motion, kinetic and potential energy, and more. Teachers will appreciate the opportunity to augment their STEM curricula while having fun at the same time. These projects are also perfect for science fairs or design competitions. Bobby Mercer has been a high school physics teacher for over two decades. He is the author of The Flying Machine Book and Smash It! Crash It! Launch It! and lives with his family outside of Asheville, North Carolina.
