Foreword

The study of physical science is an exploration of chemistry, physics, and the Earth. The CK-12 Physical Science
Concept Collection presents physical science as a set of 5 chapters, each centered around a general subject area, such
as the study of chemical interactions. Each chapter is broken down into concepts. Each concept is a mini-lesson
that addresses one specific topic or key objective. The complete CK-12 Physical Science Concept Collection is
comprised of 297 concepts.
