Introductory Principles in Physics (IPP), 2nd edition is an outstanding, STEM-strong, mastery-based physics text ideal for 9-11th grade. While Centripetal Press advocates the advantages of the “physics first” high school science sequence, IPP is suitable for use in any 9-11th grade context.
IPP contains two optional chapters — Buoyancy and Pressure and Geometric Optics —that contain more challenging concepts and mathematical application for use in an upper grade classroom or homeschool.
Like all Centripetal texts, IPP includes an intentional integration of related subjects along with the physics: mathematics, history of science, written and verbal communication, tie-ins to humanities, and even a little bit of epistemology (philosophy of knowledge). For this reason, the book is a favorite among humanities-based, STEM-focused, Classical-model schools, or any school that simply wants an enriching, effective learning tool for high school physics.
