Description

The Delta Science Collection States of Matter introduces students to matter and its physical properties. Students learn about three states of matter: solid, liquid, and gas. They read about changing from one state to another by melting, freezing, evaporation, and condensation. Students meet two scientists who work with matter in different states—one at a crayon factory and another in Antarctica. Finally, they discover how heating gases keeps a hot air balloon afloat.

Delta Science Readers are 16-page nonfiction books for students with informative, engaging full-color photos and graphics that present key science concepts and vocabulary.

Using science material they promote reading in the specific content area. Readers present key science content and vocabulary found on most state tests and support and extend the experiences and content of hands-on activities. They also help students develop informational literacy skills while promoting scientific inquiry.

1. Think About...
   Contains key information about the unit topic
2. People in Science
   Provides historical biographies, careers in science
3. Did You Know?
