Conceptual Chemistry, Third Edition features more applied material and an expanded quantitative approach to help non-science majors understand how chemistry is related to their everyday lives. Building on the clear, friendly writing style and superior art program that has made Conceptual Chemistry a market-leading text, the Third Edition links chemistry to the real world and ensures that students master the problem-solving skills they need to solve chemical equations. New Spotlight Essays at the end of the first 12 chapters focus on topics such as Nanotechnology and Extending the Human Lifespan that help students connect what they learn in the classroom to what they see in the world. More in-depth coverage of stoichiometry and gas laws, along with better identification of various end-of-chapter problem types and new collaborative problem sets, provide increased mathematical rigor for instructors who want to emphasize quantitative understanding in their course. The Third Edition also features the most comprehensive supplements package on the market: Each new copy of the book is packaged with the Conceptual Chemistry Alive DVD, an engaging, multimedia course that contains mini-lectures, demos, animations, and other interactive exercises. Two new supplements, an Activities Workbookand a Student Resource Guide give students more opportunity to practice the concepts they learn in lecture. In-text Concept Checks pose a question for students to answer immediately. These questions reinforce ideas just presented, before a student moves on to new concepts, and help students synthesize ideas from across the chapter. Hands-On Chemistry activities allow students to witness chemistry outside a formal laboratory setting. These can be performed using common household ingredients and equipment. Most chapters have two to three Hands-On Chemistry features, which lend themselves well to distance learning or in-class activities. Special icons identify the activities that can also be viewed on the Conceptual Chemistry Alive! DVD. Calculation Corners appear in select chapters. They are included for instructors who want their students to practice the quantitative reasoning skills involved in chemical problem solving. In each, an example problem and answer shows students how to perform calculations related to concepts in the text. After these examples, the Your Turn section gives a similar problem for students to solve. None of the calculations involve skills beyond fractions, percentages, or basic algebra.
