The student edition is divided into four units -- two for chemistry and two for physics. The chemistry units move the student from matter and what it is made of to how matter interacts in chemical reactions, nuclear changes, solutions, and acids and bases. In the physics units, students learn about how matter and energy move and why they move; they study the many forms of energy and how energy moves throughout the world. All this is a quest to understand the world that God created. Clear, scientifically accurate images help them picture the structures they study. Case studies, worldview sleuthing activities, mini-labs, ethics boxes, and questions help students think like scientists and view physical science from a biblical perspective. - Publisher.
