We use machines every day, but most of us don't understand how they work. When they break down, most of us have no idea how to fix them. Mechanics are the masters of machines. Readers learn that mechanics work on vehicles, including cars, boats, and buses. They use special tools to take them apart and fix what's wrong, and they use their experience and technology to diagnose problems. They often work long hours, sometimes in bad weather, to get us where we need to go. Your readers will see that mechanics keep our world moving and growing.

If it were possible to shrink down and take a tour of a human body, would you want to go? Readers will get that chance when they explore the body of a guy named Marty, who will let them check out the body systems that keep his heart beating and his body moving every day. With the help of a tiny ship that goes through his ears and all the way through his digestive system, readers will learn exactly what they are made of with this great book.

The sun is responsible for all life on Earth, but what exactly is it? Our star is an amazing force that can be as dangerous as it is important.

They’ll learn about the life cycle of a star and see just how long we have until we have to find a new planet to call home. Don’t worry, they’ll be happy to learn that (hopefully) we have millions of years left!
