100000 WHYS: HOW THINGS WORK: A Full-Color Visual Encyclopedia of Big Questions, Smart Answers About the Hidden Science Inside Machines, Gadgets, ... WHYS Full-Color Encyclopedia Collection)

THE MODERN WORLD IS FULL OF HIDDEN SYSTEMS Kids use machines, gadgets, transportation, electricity, and connected technology every day but what is actually happening inside them?

100000 WHYS: How Things Work transforms everyday technology into clear, visual STEM lessons. This full-color visual encyclopedia and extracurricular enrichment resource helps kids understand not only what things do, but how parts, signals, forces, energy, and processes work together.

Every topic follows a visual-thinking pathway:

SEE THE PARTS → FOLLOW THE PROCESS → UNDERSTAND THE SYSTEM

Kids learn to investigate how something works:

INPUT → PARTS → PROCESS → OUTPUT

A washing machine becomes a system of water, detergent, motion, drainage, and spinning. A touchscreen becomes a sequence of input, detection, processing, and response.

Kids discover that familiar things work because parts perform different jobs, exchange signals, transfer energy, and operate in sequence.

BUILT FOR EXTRACURRICULAR ENRICHMENT This book extends learning beyond lessons, worksheets, and trivia.

It strengthens:

Systems thinking by showing how parts work together
Cause-and-effect reasoning by following what happens next
Connection thinking by linking mechanisms and systems
Visual literacy through arrows, labels, cutaways, and maps
Problem-solving by exploring each part’s role and possible failures
Real-world STEM understanding
Independent curiosity through further investigation

They do not simply learn that an airplane has wings. They investigate thrust, airflow, lift, gravity, speed, and balanced forces.

A VISUAL LEARNING SYSTEM THAT MAKES COMPLEX IDEAS CLEAR INSIDE VIEWS AND CUTAWAYS
See hidden parts inside appliances, vehicles, electronics, tools, and machines.

HOW IT WORKS
Follow mechanisms through clear three-to-five-step sequences.

SYSTEM SNAPSHOTS
Break each topic into:

Input • Parts • Process • Output

ZOOM-IN VIEWS
Explore circuits, sensors, gears, pixels, motors, filters, lenses, batteries, valves, and wires.

SIGNAL-FLOW MAPS
Trace information through phones, Wi-Fi, GPS, microphones, remotes, smart speakers, and networks.

FORCE-AND-MOTION DIAGRAMS
See how lift, gravity, friction, pressure, buoyancy, thrust, and balance make objects move.

BIG SYSTEM MAPS
Discover how power grids, water networks, airports, hospitals, data centers, and cities depend on connected parts.

SMART ANSWERS
Read clear explanations without dense textbook language.

READING BECOMES ACTIVE DISCOVERY Try Noticing This prompts connect science to safe, everyday observations.

Mini Quizzes check understanding.

Stump Your Grown-Up questions encourage conversation, prediction, and shared discovery.

Myth Checks correct misunderstandings, such as refrigerators “making cold,” batteries being filled with electricity, or gravity disappearing around satellites.

Quick Facts make important ideas memorable.

Challenges and Think & Check activities ask kids to compare parts, predict outcomes, and consider what happens when a system changes or fails.
