Spanning multiple topics, these Science Readers aim to develop content-area literacy in the sciences. An engaging layout with bright colors, large graphics, and informational sidebars invites readers to explore the text, which builds in concepts. Composition of Matter begins with a definition of matter itself before describing atomic structure, elements and the periodic table, and molecules and reactions. These explanations lead to the importance of studying chemistry and how matter acts. Each volume includes a glossary and extends the discussion with concluding experiments and thought-provoking questions. Solid science basics for individual or classroom use.
