Description: Take the Rube Goldberg challenge! 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 . Middle schoolers love the wacky machines designed by Goldberg, which were based on complicated chain reactions used to accomplish very simple, sometimes ridiculous, tasks. Young engineers are invited to invent, design, create, and play as they make their own Rube Goldberg machines using the engineering design process and lots of imagination!

Review Quotes: 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."
