States of Matter
Understanding the concepts of solids, liquids, and gases is central to the early science curriculum. States of Matter uses simple text vetted by a science curriculum consultant and a reading consultant to introduce beginning readers to these important concepts. Each book features a strong photo-text match and clear, full-color diagrams to enhance comprehension, while the simple text builds vocabulary and reading skills.
