Each day, you encounter solids, liquids, and gases. How can you tell which substance is which? My Physical Science Library: Solids, Liquids, and Gases teaches young readers how to describe and classify materials based on observable properties such as color, texture, size, and shape.

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.
