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 different 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.

Written and researched by Maddie Moate, the star of CBeebies Do You Know?, this book is packed with awesome facts and key STEM concepts - perfect for nurturing curious minds aged 6 and above.​​​
