Young people intuitively understand that matter takes different forms – water, for example, can be liquid, solid ice, or gaseous steam. This book will give readers a deeper understanding of the different states of matter. Through colorful photographs and lively discussions of familiar materials, readers will be drawn in to learn about matter’s many forms. Topics include
• understanding matter, mass, volume, and density
• differences between solids, liquids, and gases
• how matter passes from one state to another
• properties of matter, such as hardness and viscosity.
