Take a closer look at the different engineering fields and skills needed for our world to function. Energy powers everything in the world around us. But where does this energy come from? Discover the machines that engineers have created to convert energy into electricity, different types of electrical circuits, and how engineers design buildings to make them more energy-efficient. You're the engineer!

Take a closer look at the different engineering fields and skills needed for our world to function. Where would we be without machines? Mechanical engineers design all sorts of complex machines to make our lives easier, but behind every ingenious invention are six simple machines that make all the others possible - levers, pulleys, wheels, planes, wedges and screws. Find out how they all work, and how engineers put them to use in extraordinary ways. You're the engineer!

Take a closer look at the different engineering fields and skills needed for our world to function. Whatever engineers are designing and building, they have to think carefully about what it should be made of: wood or glass, plastic or metal, fabric or ceramic? Find out what properties help engineers make these choices and how materials are mined or made. Discover what amazing materials engineers are inventing to meet new needs - now and in the future. You're the engineer!

Take a closer look at the different engineering fields and skills needed for our world to function. Humans wouldn't get very far without cars, buses, boats, trains, and planes. But who designs and builds all these amazing machines - and how? Discover the many ways in which transportation and aerospace engineers keep us on the move, and find out where the future might take us thanks to cutting-edge ideas such as smart roads and space tourism. You're the engineer!

When Remya Jose had to spend many hours washing her family's laundry by hand, she invented a pedal powered washing machine that could finish the chore in only 20 minutes! When Tripp Phillips' Lego creations kept falling apart, he developed a glue strong enough to hold his creations together that would wash off when he was ready to build something new! And when Fatima Al Kaabi didn't have anyone willing to teach her about robotics, she turned to the internet to teach herself all the skills she needed--and created multiple crowd-pleasing robots in the process! From Popsicles® and swim fins to robots and glitter shooting prosthetics, Kailei Pew's middle grade nonfiction debut is full of fun and inspiring stories, illustrated by Shannon Wright, about real kid inventors who proved that even the youngest people can change the world.

Kids today are growing up with social media and life online, which is a big change from how their grown-ups grew up! Life online isn't a bad thing, and it isn't necessarily a good thing either. This book shows kids that how you hang out online only tells the whole world who you already are, and that when you show up authentically, creatively, and kindly, you can change the world!

Children may not realize it, but they use models everyday. This book shows children how models represent things to help humans understand them better.
