This online textbook contains explanations, examples, and practice problems for many topics in introductory physics, including Mechanics, Matter, Thermal Physics, Waves & Optics, E&M, and Modern Physics.  It is especially appropriate for new and crossover teachers.  (Open Website)

This is a freely downloadable physics textbook exploring mechanics, thermodynamics, electromagnetism, special and general relativity. Although conceptual and non-mathematical, the text uses some of the most modern research questions as examples. The three main sections of the book cover classical physics, quantum physics, and unification theories and spacetime.  (Open Website)

This web site contains a free textbook for a non-mathematical Conceptual Physics course aimed at high school or beginning college students.   The author adopts a modern approach to understanding physics revolving around the concepts of symmetry and conservation laws.  Specific topics include Conservation of Mass and Energy, Conservation of Momentum, Relativity, Electricity and Fields, The Ray Model of Light, and Waves.  (Open Website)

This collection includes a variety of resources for teaching both introductory physics and AP physics at the high school level.  It contains lesson plans, homework assignments, labs, lecture presentations, and classroom demonstrations in an easily navigable format.  Topics include classical mechanics, thermal physics, ray and wave optics, electricity and magnetism, and modern physics.  Answers to the homework problems and sample tests are also provided.  (Open Website)

This website offers lesson plans on more than 70 demonstrations for use in introductory physics classrooms.  All demos have been fully tested in the classroom and were selected for inclusion because they are enjoyable, thought- provoking, and require minimal set-up.  Historical anecdotes and commentary add to the depth of this unique resource.  (Open Website)

This collection, written by a high school physics teacher, contains detailed lesson plans for more than 50 hands-on labs on the topics of safety, measurement, mechanics, sound and light, and electricity.  Activities include reproducible data record sheets, student work assignments, and short-answer queries.   Labs are also organized into a week-by-week block plan to aid beginning teachers with a context for using each activity.  (Open Website)

This collection contains links to web sites, lesson plans, simulations, and other resources for high school physics teachers.  Resources are grouped according to topic and tied to national standards for physics education.  (Open Website)

This unique resource is a large collection of capsule reviews of material covered in introductory physics. The subjects are organized in flow charts that make it easy to move from one topic to a related one.  (Open Website)

This resource is a collection of interactive java applets for introductory and intermediate physics.  Topics range across a broad spectrum, including electrostatics, E&M, Optics, Waves and SHM, and Orbital Motion.  (Open Website)

The TEAL (Technology Enabled Active Learning) project at MIT merges lecture, cooperative learning, and computer simulations of electromagnetic phenomena.  Designed for teachers of introductory physics, it is the pedagogy currently followed at MIT for freshmen physics students.  Comprehensive course notes accompany the simulations.  (Open Website)

This collection offers well-organized sets of java simulations relating to physics for high school classroom use.  The subjects include mechanics, waves, electricity, optics, thermodynamics, relativity, atoms, and nuclear physics.  The simulations are designed to be easily manipulated by high school students.  (Open Website)

This NSF-sponsored collection provides instructions for 24 inquiry-based high school physics labs available for free download.  Topics include Mechanics, Waves, E&M, and Optics.  The materials on Atomic Force Microscopy and Resistance of Atomic Wires are among the few web-based resources on nanophysics designed specifically for high school students.  (Open Website)

This page is a set of online resources classified into four units:  Motion, Circular Motion, Waves, and Light.   It was developed  by a team of high school physics teachers, who mined the Internet for top simulations and also created their own Physlet adaptations and Power Point presentations.  It could serve as a great tool for incorporating technology with limited time for planning.  (Open Website)

This page is Part II of the resource directly above.  This collection contains four units typically taught in the latter half of a beginning high school physics class:  Energy and the Conservation Laws, Electricity and Magnetism, and Modern Physics.  It was developed by the same team of teachers who created Physics 20, and also contains a variety of multi-media tools to aid in concept building.  (Open Website)

Lecture Materials, Problem Sets, Curriculum
Teachers who want to update content knowledge on waves will appreciate these illustrated lecture notes on wave motion and behavior, sound waves, boundary conditions, and the Doppler Effect.  Be sure not to miss the animated spreadsheets in Excel format, which can be customized and used in the classroom.  Also included are sets of printable student problem sets and study guides on wave essentials.  (Open Website)
