An Introduction to Physical Science presents a survey of the physical sciences--physics, chemistry, astronomy, meteorology, and geology--for non-science majors. Topics are treated both descriptively and quantitatively, providing flexibility for instructors who wish to emphasize a highly descriptive approach, a highly quantitative approach, or anything in between. Time-tested pedagogical tools address the needs of a range of learning styles: concepts to be treated mathematically are consistently introduced from three perspectives (definition, word equation, symbol notation); Confidence Exercises follow in-text Examples, giving students an opportunity for immediate practice and reinforcement; and updated Spotlight On features use figures, photos, or flowcharts to visually summarize important topics. The Twelfth Edition includes new content and features that help students better visualize concepts, master basic math, and practice problem solving. In response to instructor feedback, new end-of-chapter problems appear throughout the text...
