Crazy Contraptions: Build Rube Goldberg Machines that Swoop, Spin, Stack, and Swivel: with Hands-on Engineering Activities - eBook
Why use a simple hand motion to wipe your mouth when you can build a machine to do it for you? Toppling dominoes, rolling marbles, racing balloon cars, springing catapults, and whizzing zip-lines are all elements used to build Rube Goldberg machines in Crazy Contraptions: Build Rube Goldberg Machines that Swoop, Spin, Stack, and Swivel with Hands-On Engineering Activities. The book introduces kids ages 9-12 (and beyond!) to the wacky machines designed by Goldberg, which were based on complicated chain reactions used to accomplish very simple, sometimes ridiculous, tasks.
Through contraptions, the book discusses the basics of physics, including force, motion, and work. Each chapter introduces one of the six simple machines a nd how they can be used in Rube Goldberg contraptions?inclined planes, levers, wheels and axles, wedges, screws, and pulleys.
Kids are challenged to design, build, and evaluate dozens of increasingly complex contraptions that do things like unscrew a lid, turn the page of a book, and pop a balloon.
Projects use materials already in most homes and repurposing everyday items, as well as mining the recycling!
Contraption hints, essential questions, short sidebars, and links to online primary resources help readers learn the basics of force, work, motion, and simple machines, while exploring their creativity as they design and build their own crazy contraptions.
