What is density? How does it affect whether an object sinks or floats? In Density, beginning readers learn how particles play a role in comparing the density of different objects. 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 experiment with oil and water to compare density. Children can learn more about states of matter and physical science concepts online using our safe search engine that provides relevant, age-appropriate websites. Density also features reading tips for teachers and parents, a table of contents, picture glossary, and index. Density is part of Jump's States of Matter series. Index Table of contents
