Age of New Ideas Book

Grades: 3 - 6 A story, a problem, a list of possible solutions, and - Eureka! You have it! Become an inventor, and test your creative skills with an experiment or make-and-do construction. Who thought of building a catapult that could sling a cow a couple of miles over a castle wall? What made Leonardo design a parachute? Who fired the first  cannon ball, and how can a lemon power a digital clock? You can find the answers here. Then model your own inventions- from a miniature flush toilet to a cracking pop-gun and a dragon with battery-powered eyeballs. Your students can explore ten different inventions and step-by-step instructions allow them to construct the invention or experiment. Library bound, 48 pages.
