Physical Science 11th Edition
Physical Science is a straightforward, easy-to-read but substantial introduction to the fundamental behavior of matter and energy. It is intended to serve the needs of nonscience majors who are required to complete one or more physical science courses. It introduces basic concepts and key ideas while providing opportunities for students to learn reasoning skills and a new way of thinking about their environment. No prior work in science is assumed. The language, as well as the mathematics, is as simple as can be practical for a college-level science course.
The Physical Science sequence of chapters is flexible, and the instructor can determine topic sequence and depth of coverage as needed. The materials are also designed to support a conceptual approach or a combined conceptual and problem-solving approach. With laboratory studies, the text contains enough material for the instructor to select a sequence for a two-semester course. It can also serve as a text in a one-semester astronomy and earth science course or in other combinations.
MEETING STUDENT NEEDS
Physical Science is based on two fundamental assumptions arrived at as the result of years of experience and observation from teaching the course: (1) that students taking the course often have very limited background and/or aptitude in the natural sciences; and (2) that these types of student will better grasp the ideas and principles of physical science that are discussed with minimal use of technical terminology and detail. In addition, it is critical for the student to see relevant applications of the material to everyday life. Most of these everyday-life applications, such as environmental concerns, are not isolated in an arbitrary chapter; they are discussed where they occur naturally throughout the text.
Each chapter presents historical background where appropriate, uses everyday examples in developing concepts, and follows a logical flow of presentation. The historical chronology, of special interest to the humanistically inclined nonscience major, serves to humanize the science being presented. The use of everyday examples appeals to the nonscience major, typically accustomed to reading narration, not scientific technical writing, and also tends to bring relevancy to the material being presented. The logical flow of presentation is helpful to students not accustomed to thinking about relationships between what is being read and previous knowledge learned, a useful skill in understanding the physical sciences. Worked examples help students to integrate concepts and understand the use of relationships called equations. These examples also serve as a model for problem solving; consequently, special attention is given to complete unit work and to the clear, fully expressed use of mathematics. Where appropriate, chapters contain one or more activities, called Concepts Applied, that use everyday materials rather than specialized laboratory equipment. These activities are intended to bring the science concepts closer to the world of the student. The activities are supplemental and can be done as optional student activities or as demonstrations.
NEW TO THIS EDITION
Numerous revisions have been made to the text to update the content on current events and to make the text even more userfriendly and relevant for students.
The list below provides chapter-specific updates:
∙ Many new worked Examples and end-of-chapter Parallel Exercises have been added, especially in Chapters 14–24, to assist students in exploring the computational aspects of the chapters and in working the end-of-chapter Parallel Exercises.
∙ A new feature, Science Sketch, engages students in creating their own explanations and analogies by challenging them to create visual representations of concepts.
∙ Throughout the text, issues and illustrations surrounding science, technology, and society have been significantly updated, replacing descriptions of out-of-date technologies and replacing them with newer, more relevant ones.
∙ The revised Chapter 14 contains additional information on distances in space, with accompanying new worked Examples and end-of-chapter Parallel Exercises. This revised chapter also includes updated information on the future of our universe.
∙ The revised Chapter 15 includes many new images and updated information from the latest space missions. There are also many new worked Examples to assist students in exploring the computational aspects of the chapter and in working the end-of-chapter Parallel Exercises.
∙ Chapter 23 includes the most recent IPCC information on Earth’s changing climate, and its causes.
