What is a solid? What are its properties, and how can it turn to a liquid? In Solids, beginning readers learn about this state of matter and how it applies to their everyday lives. Vibrant, full-color photos and simple diagrams complement carefully leveled text to engage young readers as they learn about this fundamental physical science concept. A hands-on STEM activity invites readers to freeze and make their own fruit juice popsicles to demonstrate how states of matter change. Children can learn more about states of matter online using our safe search engine that provides relevant, age-appropriate websites. Solids also features reading tips for teachers and parents, a table of contents, picture glossary, and index. Solids is part of Jump's States of Matter series.
