Does your coat have a zipper? Did you eat breakfast with a fork? You’re using simple machines!
From butter knives to seesaws, rolling pins to catapults, we are surrounded by simple machines! Simple Machines! With 25 Science Projects for Kids astounds readers with the ingenuity they already possess and inspires them to look differently at the objects they use every day.
What do a fork and an axe have in common? How do pulleys get a flag up a flagpole? Simple Machines! introduces kids to the concept of mechanical advantage and harnesses kid-power by inviting them to build machines of their own design. This book also opens eyes and minds to the diversity of machines in their lives, and sparks the imagination with challenge, humor, and achievable projects.
Simple Machines! dedicates a chapter to each of the six simple machines that were identified centuries ago: levers, inclined planes, pulleys, screws, wedges, and wheels and axles. Kids develop analytical skills as they figure out where force is applied and what kind of work it generates. Essential questions, fascinating facts, and links to online primary sources make student-led learning fun and productive! Through science-minded STEM projects and investigative engineering experiments, kids develop critical and creative thinking skills about the roles simple machines play in our world and their importance to human civilization.
Simple Machines! is part of a set of two Explore Technology books that introduce young digital natives to the history, science, and engineering of the tech world in which we live, using hands-on STEM activities, essential questions, links to online primary sources and real-life connections
