How It Works
Series of 6 titles
Submarines dive, rockets soar to space, and computers process information. But how do these things work? In this series, readers will explore the science behind common machines and vehicles through leveled text and engaging
photographs. Special features show the machine’s parts, break down how
they work, and explain what people do to control the machine. Each book closes by discussing what future machines will look like and asking readers to join in.
