Summary
"This book introduces the concept of sound waves in a relatable, child-centered way. Readers will discover that matter must vibrate to make sound and that sound can make matter vibrate. They will also learn how sound waves are used for communication and be able to demonstrate this knowledge by creating their own sound devices"--Provided by publisher.
