Crazy Contraptions: Build Rube Goldberg Machines that Swoop, Spin, Stack, and Swivel with Hands-On Engineering Activities

Reviews

School Library Journal 
“Gr 4-6–Inspired by cartoonist (and trained engineer) Rube Goldberg, Perdew intersperses introductions to six simple machines from inclined planes to screws, explanations of Newton’s laws of motion, and projects that use these principles and tools to show energy in motion and sequential actions. The projects, which include a device for knocking down a “one-armed Lego dude” to a working catapult (or “Treat Launcher”), are all constructed from easily available materials. Most include hints or challenges aimed at inspiring tinkerers to concoct alternative designs to accomplish the same results. Along with plentiful diagrams and color illustrations, nearly every spread features a vocabulary list. Many also include one or more Q-code links to relevant videos online. VERDICT: A delight for all budding engineers in elementary grades who, as Perdew puts it, ‘like to think of complex ways to accomplish simple tasks.’”

Praise for Extinction by Laura Perdew

National Science Teachers Association Recommends
“This book uses the concept of extinction to teach a little chemistry, a little climatology, paleontology, biology (biodiversity), ecology, and a lot of geology. The science information is historical and current, drawing on three–dimensional learning, incorporating science practices to determine what factors affect extinction in general and specifically. The integration of concepts helps bring the science alive and relevant.”

“When it comes to keeping kids’ interest in a subject alive, combining hands-on activities with knowledge is key. That’s why the Build It Yourself books from Nomad Press are such great resources, not just for classrooms, but also for at-home application of new learning.”

Alexander’s Library
“Finally! A book about paleontology that begins with a geological time scale stretching from Earth’s beginning (about 4.6 billion years ago) to the present. Not only does the timeline map out eras, periods, and epochs, it also places the last five mass extinctions into context.
