About the Holiday
Today I’m featuring two books that bring the world of big machines down to size for little readers. Being introduced to the various parts of favorite machines and what they do can spark a life-long interest in engineering and its many applications!
The Book of Flying Machines
By Neil Clark
Readers join Clever Cogz and his sidekicks, Nutty and Bolt, as they get up-close to airplanes, hot air balloons, helicopters, supersonic jets, and the latest technological advances to fill the skies. Little ones who love air travel or just watching planes soar through the clouds learn all about the “clever parts” that allow these machines to ascend, fly, descend, and land.
After defining the engine, cockpit, fuselage, tail, rudder, wheels, and fins, Clark presents a closer look at the wings, with all of their moving parts “that work together to control the speed and direction of the plane.” But how does a plane stay in the air? Kids discover that a wing’s special shape allows air to travel “faster over the top than it does underneath,” and that “the slow-moving air under the wing creates a force called lift.” Clever Cogz reveals that “lift is the force that keeps an aircraft in the air.”
Now that the plane is in the air, how does it move forward? Working together, the engine and the propeller use air to create thrust, and budding engineers get to see just how this works. Next, children get to join Nutty and Bolt in a hot air balloon ride and discover how pilots use the science of hot air to make the balloon rise. They also learn the names of the various parts of these beautiful machines that make them work—and allow them to come back down.
No one can resist watching a helicopter hover overhead, and its ability to “take off and land without a run-up” makes it very useful in emergency situations. Readers get to learn about the engine, the landing skids, the rescue hoist, and the two rotors that provide the power for this unique machine while Bolt comes to Nutty’s aid on his sinking boat. Kids fascinated by speed will love learning about the various types of jets that “travel at supersonic speeds—faster than the speed of sound” and the definition of Mach 1, against which they can compare the speed of jets that fly at Mach 3.3, 6.7, and even 9.6.
Of course, kids are familiar with drones, so they’ll be eager to discover how three different types—one that can even predict storms. Finally, flying here and there powered by a jet pack may seem like science fiction, but “real ones have been built for the army, for astronauts, and for spectacular stunt shows,” including the Bell Rocket Belt, which can fly up to 60 mph (95 kmph) and the Jetman, invented by Yves Rossy, that can fly at 100 mph (160 kmph). Along the way, bits of trivia about the history and facts of air flight give kids even more information. A short quiz on the last page lets readers show off what they’ve learned.

The Book of Diggers & Dozers
By Neil Clark
Clever Cogz, Nutty, and Bolt are back in this book all about working machines. From backhoe loaders to excavators to bulldozers to the giants and the latest tech wonders, Neil Clark takes readers above and below ground to see how these machines work. Take a moment to get to know the intricate parts of a backhoe, which can lift the weight of three cars with its front loader and dig deep holes with its hydraulic-powered bucket in the back. The spinning seat in the cab makes it easy for the operator to do both jobs! What are hydraulics? Dog Clever Cogz, Nutty, and Bolt demonstrate the concepts on a backhoe and with a water gun.
Little ones know tractors belong on farms, but they’ll be surprised at how many jobs they can do using different attachments. There’s even a hole digger that makes planting trees much easier. The excavator may be best known for the tracks that wrap around sprockets and allow it to move over bumpy ground, but its bucket deserves some attention too. It has “an extra part called a thumb” that “turns the bucket into a giant claw, perfect for grabbing things.” Did you know that there are “new, electric powered excavators that will help keep our planet clean?”
The tallest machines are cranes—and “the biggest mobile crane is over 800 feet (245 m) high.” Nutty tells kids “that’s as tall as 50 giraffes standing on top of each other!” A crane’s height and power help it move objects too heavy to move any other way. When roads need fixing and repaving, it’s time to break out the road roller. These useful machines have been around since 1800, when horses pulled them. The steamroller was invented in 1865, and the diesel-powered version came along in 1950. The new road rollers are electric and better for the environment.
Fans of the bulldozer will see what a powerhouse this machine really is. With high tracks to allow it to travel through muddy ground, a ripper that claws at the ground and breaks up big lumps of earth, and a blade that can push piles of rock or sand or even knock down a building, the bulldozer is multi-functional. Whoa! Have you seen the Bagger 293? “It’s the biggest digger in the world” and its bucket wheel can dig “240,000 tons of coal a day.” It’s so big that it requires as much electricity as a whole town and needs 5 people to control it. Today, robot diggers controlled remotely, such as sensors, demolition bots, and the XE15R, are also taking on tasks in dangerous, tight, or other situations. A final quiz lets children review what they’ve learned.
Neil Clark’s fascinating looks at aircraft and the biggest machines will delight vehicle lovers of all types. His straightforward text is accessible for all ages while introducing children to vocabulary and concepts that empower them to understand the workings of not only these big machines but smaller, everyday machines as well. Loaded with information and hosted by charming characters who lend a bit of humor to the pages, Clark’s books are wonderful for dipping into again and again.
Clark’s vivid illustrations clearly mark and define the parts of each machine and demonstrate how these work together to power the machine and allow it to perform its job. Nutty and Bolt are there to translate some of the concepts into ideas kids are already familiar with (for example, Nutty wears big shoes to demonstrate the function of a backhoe’s stabilizers). Similarly, Clark incorporates easy-to-understand graphics to explain scientific concepts like air flow and the clustering of hot and cold air molecules. Boxed information and speech bubbles add interest to the pages. One even invites kids to a “where’s Waldo” type of hunt for Nutty and Bolt near a jumbo jet.
Terrific books for introducing all children to machines, how they work, and the science behind them, The Book of Flying Machines and The Book of Diggers & Dozers would be valuable additions to home, classroom, and public library collections. Check out the other books in the series: The Book of Cars and Trucks and The Book of Space Rockets.
