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 in kindergarten to grade 2 about sound waves and how we send and receive them in order to communicate, make music, and so much more.

This 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.
