Discusses the nature, constitution, properties, and behavior of matter in its various solid, liquid, and gaseous forms. With hands-on activities.

Photographs and simple text describe the physical properties of solids.

Summarizes how water changes from a solid to a liquid and back again, and introduces related facts such as water freezes at thirty-two degrees Fahrenheit and ice floats.

Text and photographs provide a brief introduction to matter and its properties.

Learn the unique properties of solids and the conditions under which they change state.

Explores the properties of matter in its solid and liquid states, covering such topics as volume, powders, liquid thickness, melting, freezing, and separating soluble solids.

Contains simple science experiments designed to teach young students about solids and their uses and properties.

Simple yet thought provoking questions which stem from one basic question--is it liquid or solid?.
