Explain Like I'm 5

Vroom! Have you ever wondered what makes a car go? Inside every car, truck, mower, and motorcycle is a mighty little machine called a combustion engine - and this book makes it easy for kids (and curious grown-ups) to finally understand how it works.

With short chapters, friendly pictures, and the catchy four-stroke rhythm of "Suck, Squeeze, Bang, Blow," young readers will discover:

• What an engine actually is and what it does
• The science of fire, fuel, air, and spark
• The four-stroke cycle explained step by step
• The main engine parts: pistons, cylinders, crankshafts, valves, and spark plugs
• How fuel and air mix, how cooling and oil keep things smooth, and where exhaust goes
• Different engine types - inline, V, flat, two-stroke, rotary, and diesel
• Engines in cars, trucks, boats, planes, mowers, and generators
• Hybrid and electric cars, and what comes next

Packed with fun facts, a glossary, quick quizzes, hands-on "Try This at Home" activities, drawing pages, and a Certificate of Engine Smarts, this is the perfect first STEM book for kids ages 5-9.
