How Does It Work?
By Maddie Moate

In this curiosity-busting factbook, Maddie Moate&nbsp;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 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.<br style="color-scheme: unset; forced-color-adjust: unset; math-depth: unset; position: unset; position-anchor: unset; text-size-adjust: unset; appearance: unset; font-feature-settings: unset; font-kerning: unset; font-language-override: unset; font-optical-sizing: unset; font-palette: unset; font-size-adjust: unset; font-stretch: unset; font-synthesis: unset; font-variant-alternates: unset; font-variant-east-asian: unset; font-variant-emoji: unset; font-variant-numeric: unset; font-variant-position: unset; font-variation-settings: unset; position-area: unset; text-orientation: unset; text-rendering: unset; text-spacing-trim: unset; -webkit-font-smoothing: unset; -webkit-locale: unset; -webkit-text-orientation: unset; -webkit-writing-mode: unset; writing-mode: unset; zoom: unset; accent-color: unset; place-content: unset; place-items: unset; place-self: unset; alignment-baseline: unset; anchor-name: unset; anchor-scope: unset; animation-composition: unset; animation: unset; animation-trigger: unset; app-region: unset; aspect-ratio: unset; backdrop-filter: unset; backface-visibility: unset; background: unset; background-blend-mode: unset; baseline-shift: unset; baseline-source: unset; block-size: unset; border-block: unset; border: unset; border-radius: unset; border-collapse: unset; border-end-end-radius: unset; border-end-start-radius: unset; border-inline: unset; border-shape: unset; border-start-end-radius: unset; border-start-start-radius: unset; inset: unset; box-decoration-break: unset; box-shadow: unset; break-after: unset; break-before: unset; break-inside: unset; buffered-rendering: unset; caption-side: unset; caret-animation: unset; caret-color: unset; caret-shape: unset; clear: unset; clip: unset; clip-path: unset; clip-rule: unset; color-interpolation: unset; color-interpolation-filters: unset; color-rendering: unset; columns: unset; column-fill: unset; gap: unset; column-rule: unset; column-span: unset; contain: unset; contain-intrinsic-block-size: unset; contain-intrinsic-size: unset; contain-intrinsic-inline-size: unset; container: unset; content: unset; content-visibility: unset; corner-shape: unset; corner-block-end-shape: unset; corner-block-start-shape: unset; counter-increment: unset; counter-reset: unset; counter-set: unset; cx: unset; cy: unset; d: unset; dominant-baseline: unset; dynamic-range-limit: unset; empty-cells: unset; field-sizing: unset; fill: unset; fill-opacity: unset; fill-rule: unset; filter: unset; flex: unset; flex-flow: unset; float: unset; flood-color: unset; flood-opacity: unset; grid: unset; grid-area: unset; height: unset; hyphenate-character: unset; hyphenate-limit-chars: unset; hyphens: unset; image-orientation: unset; image-rendering: unset; initial-letter: unset; inline-size: unset; inset-block: unset; inset-inline: unset; interactivity: unset; interest-delay: unset; interpolate-size: unset; isolation: unset; lighting-color: unset; line-break: unset; line-height: unset; list-style: unset; margin-block: unset; margin: unset; margin-inline: unset; marker: unset; mask: unset; mask-type: unset; math-shift: unset; math-style: unset; max-block-size: unset; max-height: unset; max-inline-size: unset; max-width: unset; min-block-size: unset; min-height: unset; min-inline-size: unset; min-width: unset; mix-blend-mode: unset; object-fit: unset; object-position: unset; object-view-box: unset; offset: unset; opacity: unset; order: unset; outline-offset: unset; overflow-a
