Conceptual Physical Science Explorations

About This Curriculum
With over 200,000 copies in circulation, this widely popular high school edition of Conceptual Physical Science offers engaging analogies and imagery from realworld situations. With it, the student builds a solid foundation of understanding that becomes a cornerstone of general education and serves as a solid platform for further study in science. This text begins with a focus on the essential topics of physics upon which concepts of chemistry are then built. This sets the stage for an exploration of physics and chemistry concepts as they apply to planet Earth and then beyond in the study of astronomy.
