I'm not lying when I say this "deceptively simple machine" has made life easier over the millennia. This nonfiction STEM picture book traces the evolution of levers from ancient times to the present, detailing how they have contributed to civilization's achievements and advancements, and how it remains a crucial tool to this day.
Presented chronologically, this picture book goes all the way back to the Ice Age, when people hunted woolly mammoths with a spear thrower. The book engagingly combines Van Zandt's informative text with cute, detailed art that includes children in every spread. I recommend that kids explore each scene because Breen has made a point of capturing many activities in both the foreground and the background.
Whether used to weigh items for sale, lift heavy loads, or help a printing press operate, this ingenious invention changed our world. Be sure to read the factoids and sidebars as they are full of fascinating information.
Who knew a piece of wood could be so interesting, useful, and monumental in the history of mankind? This is the kind of book that can be read in one go or section by section. I can see parents or teachers using this book for activities that show levers in action, whether using a pair of scissors, a fishing rod, or even a seesaw! A bonus of buying this book is the step-by-step instructions for building the catapult model included.
