Waves don’t just happen in the ocean. Billions of sound waves move through the air every second. My Physical Science Library: Sound Moves teaches young readers about sound waves and how we send and receive them in order to communicate, make music, and so much more.

The My Physical Science Library collection introduces a variety of science topics for early learners based on physical science NGSS standards. From motion to energy supplied by the sun, these books present complicated information in easy-to-understand language and provide kid-friendly examples. Each book includes an activity that supports further comprehension.
