Follow Maddie Moate as she takes a look inside everyday objects and machines - from fridges to fire engines!Starting in the home, you'll find out how microwaves heat your food and how smart speakers react to voice commands. Then take a trip to the supermarket and discover how the checkout works, before heading to the playground and learning why a roundabout makes you feel dizzy!As you learn about difference machines and objects, you'll go on four mini adventures - from finding missing parts of a toy car, to preparing a birthday picnic. And there are puzzles for readers to solve too, including a spot the difference, a maze and a word ladder.The marvellous machines featured in this book range from objects in the home (including a smart speaker, a microwave, a dishwasher, a fridge and a toilet!) to machines in the workplace (a dentist's chair, an X-ray machine, a digger and a fire hose), as well as in the playground, at the shops, on holiday and beyond.Written and researched by Maddie Moa
