This web site was developed to provide an accessible, fun, and free resource that accurately communicates what science is and how it works. It was designed to help learners of all ages "re-engage" with science and appreciate the dynamic, exciting nature of the scientific process, and the human motivations that underlie it. It includes interactive tutorials on the process of science, classroom resources for teachers, and a do-it-yourself guide on how to design a fair experiment.

This webpage provides teaching resources useful for teaching introductory physics both at the college and high school level. These resources are created by the St. Louis Area Physics Teachers (SLAPT) members. They include materials shared through SLAPT workshops.

This website describes the physics, science, and math day activities at California's Great America Theme Park in San Francisco. Worksheets and curricular resources related to the park rides are available for download.

OnScreen Particle Physics, developed by OnScreen Science, Inc., is a Macintosh, and Windows 95/NT particle-chamber simulation, that lets instructors and students do real modern physics without advanced math. OnScreen Particle Physics is also great for independent study.

This web site provides small-group learning materials for teaching wave physics and modern physics to non-science-majors. To match student skills, observation, qualitative analysis, and graphical representations are used to introduce interference, discuss energy and probability, and develop an understanding of bound states, spectroscopy, modeling of molecules, and tunneling.

This web page provides a list of learning activities for Quantum Mechanics classes. Each activity includes a description and learning goals, guides for instructors, handouts or worksheets, and reflections of instructors who have used the activity when available. Included are activities for Operators, Eigenstates, Probability Densities, Stern-Gerlach Simulations, Schrödinger's Equation, and Time Evolution. This material is part of the Paradigms in Physics project at Oregon State University. This work promotes the use of active student learning in upper division physics courses. Both learning materials and learning strategies are provided to help both students and instructors.

This is a collection of introductory physics problems on topics in 20th century physics. The questions are designed for active learning classrooms and are built around research on student acquisition of knowledge. The problems vary in format and include context-based reasoning, multiple choice, estimation, and essay questions. The topics include conservation of mass and energy, nuclear decay, wave-particle duality, and spectroscopy. This item is part of a larger collection of problems, in-class questions, and interactive resources developed by the University of Maryland Physics Education Research Group.

This website contains a compilation of materials based on the Modeling Instruction pedagogical approach to teaching physics. It includes content support for teachers, model assessments, lab guides, student study guides, problems and solutions, and materials from professional physics education workshops. Materials are organized by fundamental models and encompass topics typically covered in an introductory physics curriculum. All resources are freely downloadable and may be reproduced for classroom use. The resources were developed for high school use but most are appropriate for use in Introductory Physics classes.

The Analytical Sciences Digital Library (ASDL) provides a collection of peer-reviewed web-based educational resources related to technical resources in the analytical sciences. Materials include articles, labware, educational practices, and more.

This is a collection of introductory physics problems designed for active learning classrooms. Each exercise in this collection is built around research on student acquisition of knowledge. Problems were designed to allow students to consider their own intuitive reasoning processes to help them gain deeper insights. Specific topics include Mechanics, Heat and Temperature, Waves, Electricity and Magnetism, Properties of Matter, Modern Physics, and Optics. A link is also provided to see all the problems displayed by type, such as multiple choice, qualitative reasoning, ranking tasks, context-based, essay questions, and more.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

This web side is part of the University of Virginia Physical Science Series, a collection of graduate-level courses designed to help K-12 science teachers connect content with best-practice teaching models. This item offers lesson plans and six activities to reinforce understanding of circuits, current, and electrostatics. The materials and activities are based on physics education research.

This web site contains a collection of labs for lower division college physics courses. The labs cover a variety of topics, including Newtonian mechanics, circuits, thermodynamics, waves, optics, and modern physics. Each lab includes a brief theoretical explanation of the concepts involved, a description of the equipment and procedures, and questions for the students. The labs are sorted by course and presented in the sequence used in the class. Some labs are used in multiple courses.

The multi-university project delivers modular, flexible online learning objects for introductory physics. These objects include a Java, Flash, or video application, suggested student activities, and extensive help. The simulations are designed to require students to explore the physical system and build understanding. The objects can be accessed in a coordinated learning interface, linked here, or individually.

This item offers in-depth content support for teachers, with sets of conceptual and numerical problems related to speed and velocity. It includes creative ideas for classroom investigations that integrate statistics. This is part of an online textbook in introductory physics.

This resource gives learners a framework for building a logical argument based on evidence obtained from observation. It provides models of good scientific arguments and tips for constructing an evidence-based conclusion. This web page is part of the Understanding Science project developed by the University of California Museum of Paleontology, in collaboration with a diverse group of scientists and teachers.

The Science of Hockey is the first in a series of "Sports Science" resources developed by the Exploratorium. This site takes you inside the game: you'll hear from NHL players and coaches from the San Jose Sharks, as well as leading physicists and chemists.
