Covering the major middle school sciences: Earth, Life, and Physical, the Holt Science and Technology curriculum provides a thorough, inquiry-based introduction to basic scientific concepts and principles that will prepare students for high school courses. Chapters in the Life Science Student Textbook open with a Pre-Reading Activity that helps students to organize their ideas, and a Start-Up Activity to motivate them. Each section includes Objectives, Key Terms, and a Reading Check to develop reading skills, vocabulary, and understanding. Lessons are concise, providing students with a brief explanation and examples, and are followed by a section review that covers the key idea, critical thinking skills, and math concepts. The sidebars provide quick labs and school-to-home connections, as well as links to other subjects or scientific topics. The text is enriched through additional examples, sidebars that ask students to think more deeply, and photographs or illustrated diagrams. Each chapter ends with a skills practice lab, comprehensive chapter review, standardized test preparation, and 'science in action' section. A lab book section in the back of the book provides detailed, step-by-step instructions for practice labs, including procedures and charts. 880 pages with index, glossary, Spanish glossary, reading check answers, and study helps. This secular middle-school curriculum cells, simple organisms, animals, ecology, human body systems, human health, Mendel, meiosis, DNA, evolution, and more, through an abundance of hands-on labs and interesting profiles of real-life scientists.
