Physical Changes

A plate breaks, an ice cube melts, a room is painted. Each of these is an example of a physical change. Readers are introduced to physical changes in matter. Simple explanations cover forms of matter, properties, and changes. Real-life examples illustrate important concepts. Fast facts and Words to Know sections provide additional information. Full-color images expand and support the narrative, while an activity reinforces ideas through experimentation. This book supports Next Generation Science Standards, correlating directly with the NGSS Grade 2 standard to "classify different kinds of materials by their observable properties."
