All About Sound

How do different musical instruments make sounds? How does a megaphone make sounds louder? How do we protect our ears from too much sound? All About Science introduces basic science topics using everyday objects and situations that readers can recognize in the world around them. Simple experiments are included to help demonstrate the concepts for young readers. This title looks at sound: how sounds are made, how they travel, how we hear them, and what makes a sound high or low, loud or soft.
