Behind the toaster, the toilet, the tub, the microwave, the camera, and countless other features of our everyday lives are smart ideas from smart people who executed them.

A bright idea of a book, Design It! is a great introduction to lots of satisfying careers from architecture to model making, to the pioneers - thank you, Mr. Cummings for the modern-day toilet! - and to the principles of good design that make life more pleasant. Rona Arato introduces young readers to the world of industrial design by focusing on our homes and by presenting the basics. She asks readers to be the judge: Does it do what it's supposed to (function)? Is it big enough, small enough, or light enough for the person who'll be using it (usability)? Is it safe and comfortable to use (ergonomics)? Does it look great (aesthetics)? And, is it eco-friendly? Equal parts fascinating history and eye-opening facts, Design It! makes for great reading and is a useful resource for those who are beginning to think about careers.
